What is the  difference between using selective V-meter,
https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg559526/#msg559526
and
regular V-meter  covering the same frequency range like  e.g Ballantine 323?
https://overunity.com/18913/in-russian-ekspierimienty-po-biesprovodnoi-pieriedachie-enierghii-doska-stroitieliei/msg559510/#msg559510
________________________________________

Answer:
The only  difference  is that  when we use selective V-meter we can hear the sound of the signal but we pay  a lot more  for it.

This part will  respond to the question why and how
energy, data, video,   telephony can be send  from point   A to any point B on the surface of the earth
with use of Zenneck Wave in the  Earth/ air interface.
Bill made  comment while talking about Viziv, and Dr Corum.
https://www.eevblog.com/forum/dodgy-technology/bullshit-texzon-wireless-power/msg2290227/#msg2290227

question:
What is the cavity standing wave dielectric loss of the earth?


Answer from:
Bill Beaty from University of Washington.
Quote
Down below 20KHz?   
Rule of thumb: the system-Q for the Earth's lowest resonance is commonly quoted as 8-10.   
So, any ~11Hz pulse will pass around the Earth over 8 times times before decreasing to 66%. 
(Imagine passing an AC pulse ten times across an entire a continent-wide power grid, with losses only 33%.)
Wesley's response:
cavity standing wave  refers to resonant standing waves between opposing walls of the cavity.
A cavity resonance occurs inside a conductive enclosure when energy is generated at frequencies which correspond to the resonant frequencies of the enclosure
That may be seen as  cavity between ionosphere and Earth and
distribution of electromagnetic  field in that resonant cavity.
and closest example may be your home microwave:
https://youtu.be/VR6nD6Iygso?t=95
https://www.sciencedirect.com/topics/earth-and-planetary-sciences/cavity-resonator
https://www.laird.com/sites/default/files/2019-07/Dampening%20Cavity%20Resonance%20Using%20Absorber%20Material.pdf
 
In regards to Tesla Coil tilting Wave into the Complex Brewster Angle  you have made  absolutely incorrect assumption:
 the standing wave must be seen as:
-distribution of electromagnetic field in a resonant cavity between Tesla Coil Top capacitor  and  partially conductive medium Earth  (dielectric is Air)- for Earth/Air  Interface.
-distribution of electromagnetic field in a resonant cavity between Tesla Coil Top capacitor  and conductive medium Aluminum foil    (dielectric is Air)  for Foil/Air  Interface
-distribution of electromagnetic field in a resonant cavity between Tesla Coil Top capacitor  and dielectric slab (another dielectric is having different dielectric properties ) for
  two different dielectric slabs interface

Q of the earth doesn't apply to Zenneck wave in the interface.
It is like talking about  inverse  square law that applies to free space but doesn't  apply to  waveguide.
And Zenneck wave exists only in the special kind of 2D waveguide known as INTERFACE
----------------------------------------------------------------------------------------------------------------------

Bill Beaty from University of Washington.
Quote
The Corums (the Tesla-phile engineers behind the Viziv tower) published an engineering analysis in the early
1990s that showed that Tesla's system would still work, even with a Q that low.
Wesley's response:
Dr Corum filed his provisional application  in 2007 describing device  utilizing Zenneck wave   in the interface.
the link you never  send us to  was from  1990 - so  this revelation can't be taken as evidence it is  about different animal.
-------------------------------------------------------------------------------------------------------------------------
Bill Beaty from University of Washington.
Quote
Their main point:  when the system is in operation, the Earth's losses, (the low Q,) represents a constant loss independent
of throughput, basically a resistor parallel to the power supply.   For a large system, the loss would be ?tens? of megawatts.   
But if we keep the operating voltage always the same, then these Earth-losses remain constant, no matter how much
wattage is being drawn by the distant receivers.   Just make sure to sell gigawatt-rates of energy to customers,
if your grid losses are constant megawatts. 
Wesley's response:
Nothing that is related to electromagnetic wave in free space can be applied  to surface wave  known as Zenneck wave.
 It is entirely incorrect  thinking pattern.
----------------------------------------------------------------------------------------------------------------------------

Bill Beaty from University of Washington.
Quote
Tesla system isn't made of thin wires.  It's planes.The analog to "cable resistance" apparently is insignificant,
when compared to that parallel leakage in the air between the high voltage and ground.
Wesley's response:
The system of Dr Corum specifies that  distance from top capacitor to the earth  must be minimum  4x  size of that  top capacitor .
there is  no leakage  not sparks allowed . look at the picture
---------------------------------------------------------------------------------------------------------

Bill Beaty from University of Washington.
Quote
1990s Sutton/Spaniol paper from NASA where they built an unusual exotic antenna, and measured Q-values in Shumann-lines
with values of many hundreds.  Not ten!   The greater VLF research community has never accepted this. 
These results are still maverick/fringe, and like the Corum papers, banished to Tesla conference publications.

Wesley's response:
I myself was in NASA programs also as Principal Investigator. . There is to much risk and to much scrutiny to  make  unsustainable claims there.
I assume you Bill  have never  participated  in them. Money  there is insured with your own assets before you'll get a penny.
Your  ironical  criticism of Dr Corum papers  is just the matter of personal preference . I also don't care  much/ at all /about publicity nor its level.
You want fame ..?  I don't not it matters to me.
But again  you are talking about  antenna and its Q.
https://www.goodreads.com/book/show/4548194-q-of-the-earth
Zenneck wave doesn't travel inside or above the earth . It travels inside of the earth /air  INTERFACE 2D space, fallowing curvature
of the earth.
For me you are  a great brain  having  such  deficiency in the direction you talking position about. the Zenneck Wave.
I'd appreciate if you  take your time and   view this.:

INTERFACE:

_____________________________________________________
INTERFACE is the  high speed  "highway" for Zenneck Wave to Travel.
Interface traps inside  the Electromagnetic  Wave and  allows  it to  travel only if  that wave is taking the form
suitable to travel in the INTERFACE. That form  is called - TM mode.

TM mode: Transverse magnetic waves, also called E waves are characterized by the fact that the magnetic
vector (H vector) is always perpendicular to the direction of propagation.
understanding-tem-te-and-tm-waveguide-modes


INTERFACE is a special form of waveguide that  looks like 2D space to our eyes.
Waveguide is  a structure that guides waves, such as electromagnetic waves.
https://en.wikipedia.org/wiki/Waveguide
Quote
hollow conductive metal pipe used to carry high frequency radio waves, particularly microwavesDielectric waveguides are used at higher radio frequencies,
and transparent dielectric waveguides and optical fibers serve as waveguides for light.
  In acoustics, air ducts and horns are used as waveguides for sound in musical instruments
and loudspeakers, and specially-shaped metal rods conduct ultrasonic waves in ultrasonic machining.

The Zenneck wave,
Zenneck surface wave or Sommerfeld-Zenneck surface wave is an inhomogeneous or non-uniform electromagnetic plane wave incident
at the complex Brewster angle onto a planar or spherical boundary interface between two homogeneous media having different dielectric constants.

types of INTERFACE ,
Interface is seen as "two dimensional  2D" space and is always made from two  different  materials :
a- dielectric and  different  dielectric- both having different  dielectric  constants)
e.g
-any combination of two  dielectric slabs  such as  Teflon and  ceramics, or paper, or mica, or glass,
-or liquid over solid dielectric  such  as: Distilled water, transformer oil,
-or gas over solid dielectric
Dielectric gases such as : nitrogen, dry air, helium, (various metal oxides,) etc.
A perfect vacuum is also a dielectric.


b- dielectric and conductive medium.
e.g
-dielectric  Air(gas) over  solid  conductor( aluminum, copper)
- solid dielectric  e.g Teflon over solid conductor e.g copper
-wire as conductive medium coated with dielectric. Goubau- Sommerfeld Line
  https://en.wikipedia.org/wiki/Goubau_line
  https://www.jensign.com/wire/calc/params.html   - practical tool !!!

c- partially  conductive medium  EARTH and  gaseous dielectric AIR.

Properties of Interface :

a.- The interface has no thickness, so it is 2 D (two-dimensional space).
In our case, the interface can be made of air touching the Earth. this means that there is no gap between this air and the earth, and this space is two-dimensional
b.- INTERFACE has certain chosen by us impedance  or naturally present  impedance in natural interface.

This is the answer part A of  point 3

Add 3

Electromagnetic wave   is often seen as wave in free space.
  Radio waves have the ability to pass through the atmosphere and vacuum space.
Free Space means air, outer space, vacuum, or something similar.

Electromagnetic wave in  Free Space  suffers significant losses  due to Inverse Square Law
https://en.wikipedia.org/wiki/Inverse-square_law

However Inverse Square Law doesn't apply to Waveguides:

The more accurate answer is here:
The power of the wave falls with the distance R from the source as the square of the distance (inverse square law).

However a waveguide confines the wave to propagate in one dimension, so that, under ideal conditions,
*the wave loses no power while propagating.*
Due to total reflection at the walls, waves are confined to the interior of a waveguide.
https://en.waveguide.

So in easy
but definitely not  accurate language :
 when we have  10km long water pipe  on the slope all of the water  put into it must go out.
Nature pay for gravitation force  pushing it down the pipe.
Electromagnetic wave as
quantum phenomena must  move with the speed of light in  free space  or at little slower speed in  given medium.

This is the answer part B of  point 3
https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg560251/#msg560251

One of types of waveguide is the  INTERFACE
The types of INTERFACEs   are explained here:
https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg560166/#msg560166


Easy explanation:

Water:
If we want water  to flow in 10km long pipe on the  slope  we must  deliver it to this water pipe,
The pipe is the trap for that water  containing it inside and allowing it to flow in  one direction only
The energy  of that water is increasing due to gravitation force.
well..its potential energy is converted into kinetic energy.

Electromagnetic wave:
The electromagnetic wave must be delivered to waveguide or its special type - the INTERFACE, in order to propagate in it.
The waveguide  is the trap for that wave  containing it inside and allowing to flow inside.
There are  no losses in *ideal waveguide* despite its length.
____________________________________________________________________________________________



Important is how we deliver electromagnetic wave  to  the Interface and  how we prepare this wave  to be able to  travel inside of it.

Easy explanation:
Water:
Water can flow in the water pipe if it is  not frozen and diameter of the pipe is  satisfying our needs for water.
And we want water for free  from nearest waterfall.
So we make the right pipe at  the right slope

Electromagnetic wave:
INTERFACE is a type  of a Waveguide and is a trap  for electromagnetic wave.So we make the right Waveguide/INTERFACE 
or
we use the Waveguide/INTERFACE   shown to  you by some American guy  from New York USA  (name Wesley)
This waveguide  doesn't cost you any money.
But now we need to deliver the  right electromagnetic wave at right form and frequency  accepted by  this waveguide- INTERFACE .
and that will be:

-right        frequency
-
right     
phase
-
right       
polarization
-
at right
  angle

This is the answer part C of  point 3
https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg560251/#msg560251


Preparing electromagnetic wave to travel in waveguide or  its special kind the INTERFACE:

If we have ready to use Interface  "We either use it or lose it."
So don't install the new shiny  transmission from the  heavy truck into small Toyota We need the right transmission   for  Toyota we already have.

___________________________________________________________________________


FREQUENCY:

Electromagnetic wave needs to have the  right frequency for existing  Waveguide or  one of its  forms - the Interface.
The higher the frequency the smaller in diameter the waveguide  can be, or the INTERFACE can be much different and using different materials.
We operate at very low frequencies  however Zenneck Wave works at all frequencies and  is  named differently.
Zenneck wave propagates best at ELF and VLF frequencies up to about 35 kHz, and would lose its advantage as frequency rose above that point.
http://www.tfcbooks.com/articles/tws4rev1.htm


From Wesley:
We were  working with my team at frequencies from :
52MHz.. good only for   copper or aluminum foil as conductive medium   and air  as  dielectric
1.8MHz  good  only for   water as partially conductive medium  ( some ground but short distance <5mile) and air  as  dielectric
137kHz good  only   as partially conductive medium  ( some ground but short distance <35mile) and air  as  dielectric
20kHz   good for earth as partially conductive medium  (  ground  distance unlimited) and air  as  dielectric
17.2kHz extremely good for  earth as  partially conductive medium  (  ground  distance unlimited) and air  as  dielectric



_________________________________________________________________
The main group of waves of our interest is :
SURFACE WAVE
 
Below you have  picture of   most dominant  Surface waves that are contained inside  some sort of  Waveguide or its  special form the INTERFACE.

So is with Electromagnetic wave:
The electromagnetic wave must be delivered to waveguide or its special type - the INTERFACE, in order to propagate in it.
The waveguide  is the trap for that wave  containing it inside and allowing to flow inside.

One concept missing from most modern research, more so science, relates to quality.
In fact all the greatest free energy inventors were obsessed with the properties and qualities
of things relative to other things. So much that they often ignored the physics preoccupied with
math and equations or measures of something.

I see many attempting to quantify the phenomena, Quanfity: express or measure the quantity of.
Where quality is a very different beast, Quality: the standard of something as measured against other
things of a similar kind. I found this really neat how all the successful free energy inventors had such a different perspective than most.

With respect to your water analogy quality matters. Now imagine a pipe which carries water and we know each discrete quantity
of water is attached to each other part as a continuous fluid. However Viktor Schauber claimed that by separating the whole into parts,
moving them in spiral concentric flows and adding air the fluid became discontinuous.
As such each part is no longer bound to all the others and each could move freely within certain constraints.

This is analogous to an impulsive electrical flow which is unlike most wave forms we are familiar with.
This is true because the flow is discontinuous and separate from the other parts constituting the "flow" of energy.
Can you see the difference in the qualities of the disturbance?. One is always bound to every other part as is normally
the case where a truly impulsive flow is not. Each part becomes distinct in it's own right and it is this quality
which allows it to interact with other fields and forces which may be present within the system.

Not unlike you and myself, we are unique and do not follow the same path as others. We take "the road not taken" and that has made all the difference...

AC

This is the answer part D of  point 3
https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg560251/#msg560251
Preparing electromagnetic wave to travel in waveguide or  its special kind the INTERFACE:


Tesla Tower is an air transformer.
Air transformer is the transformer that is made from  coils only with no metal core
The core of the transformer acts as a support to the winding in the transformer. It also provides a low reluctance path to the flow of magnetic flux.
The core of the transformer  in modern times is made  no longer from permalloy plates  but from  ferrite material and is usually  in form of Closed  Loop.
Permalloy is a nickel–iron magnetic alloy,  with about 80% nickel and 20% iron content.
Closed Loop is  shape of core making magnetic  flux to be able to  travel in it.
However one of secrets of  replication of Dr James Corum device is use of ferrite bars.

That experimentation and learning curve is  mandatory step needed to learn how to extract energy from Schuman  Waveguide and this is our  FE.
I'm probably not going to talk about it at all or in very much critical moment of my writing. !!!!!
 :)

___________________________________________________________________________



PHASE:
There are two different factors  of phase not directly related but related in time sequence:

a.-

Phase relation in Tesla Coil
Explanation:
In Tesla Coil we are dealing with standing wave
Standing Wave

is a wave which oscillates in time but whose peak amplitude profile does not move in space.
https://en.wikipedia.org/wiki/Standing_wave
That wave will oscillate vertically between Top Capacitor of Tesla coil and  the ground.
Top Capacitor is a top plate on the top of Tesla coil forming  capacitor  with another plate- the ground.
 
b.-
The complex longitudinal propagation phase constant along the Earth's surface for the Zenneck surface wave
Explanation:
http://www.tfcbooks.com/articles/tws4rev1.htm


Conclusion:

We have few  ways to  make  Wave tilt into  Complex Brewster Angle  ( in our case this would be complex  Brewster Angle)
We can do it by:
-lowering or lifting up the Top capacitor
-or playing with the  phase.


source of information:
there is plenty in my writing about :
-Complex  Brewster Angle
-and phase relation.

You may start  from here:

Preparing electromagnetic wave to travel in waveguide or  its special kind the INTERFACE:


POLARIZATION



To explain what is polarization and why it is important to us  we need to to touch some basic knowledge 
and point at similarities to visible light.

Quote
The visible spectrum is the portion of the electromagnetic spectrum
that is visible to the human eye. Electromagnetic radiation in this range
of wavelengths is called visible light or simply light.
A typical human eye will respond to wavelengths from about 380 to about 750 nanometers.

Light is electromagnetic wave and has frequency measured in Hz or nm.
 Electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields.


Our wave we use to transfer from point A  to point B is :
-  exactly  the same  electromagnetic wave but differing from light  with frequency
Our wave we extracted  from Schumann Waveguide by our receiver  is:
-  also  exactly  the same electromagnetic wave but differing from light  with frequency
That  electromagnetic wave  is invisible to our eye acting as receiver only to visible light .

Polarization is lossy but not always  as much:
energy loss can be partially avoided with the use of special filters, with the same filtering effect
but that, based in a different filtering technology,

This is the answer part F of  point 3

Preparing electromagnetic wave to travel in waveguide or  its special kind the INTERFACE:


POLARIZATION

we continuing with  explaining polarization

_________________________________________________________________
Polarization of  Electromagnetic Wave

Quote
An electromagnetic wave such as light consists of a coupled oscillating electric field and magnetic field
which are always perpendicular to each other; by convention, the "polarization" of electromagnetic waves
refers to the direction of the electric field. In linear polarization, the fields oscillate in a single direction.
https://en.wikipedia.org/wiki/Polarization_(waves)

So in every  electromagnetic wave we have oscillating :
electric field
and
magnetic field
which are always perpendicular to each other

_________________________________________________________________
Let's look at  source of  electromagnetic radiation from perspective of polarization.


POINT SOURCE:
https://www.bing.com/search?form=MOZCON&pc=MOZI&q=point+of+source
source of light can be considered a point source if we have e.g lightbulb.

We can draw spheres  around it to image  this radiation.

Light as electromagnetic wave is radiating in all directions in space around it equally and this radiation is called spherical


LINE SOURCE:
line source, as opposed to a point source,   is a source of electromagnetic radiation that emanates from a linear (one-dimensional) geometry.
Source of light can be considered a line source if we have e.g fluorescent light bulb 2ft long.
-if we place this fluorescent lightbulb vertically we can see that  light is not radiating to the top and the bottom  of it but is seen all around  it.
We can draw  cylinders  farther away all around this fluorescent  2ft long lightbulb to image  this radiation.Light as electromagnetic wave is radiating
equally in cylindrical pattern in space around vertically  placed fluorescent lightbulb 2ft long 
and this radiation is called cylindrical

_________________________________________________________________
VERTICAL and HORIZONTAL POLARIZATION

if we now take this vertical:
-  2ft long  lightbulb
   or
- vertical antenna
   or
- vertical Tesla Tower
 We see that this  cylindrical pattern of radiation is at 90 degrees to the horizontal ground.
 We call it
Vertical Polarization.
Note:  in vertical antenna we have vertical polarization but electromagnetic
           wave is propagating horizontally farther away from it.

--------------------------------------------------------------------------------------------------
Although  Tariel Kapanadze didn't use obvious vertical polarization :)
our experimenter  would use  vertical polarization only.

---------------------------------------------------------------------------------------------------
Propagation of electromagnetic wave in Free Space always suffers significant losses  due to Inverse Square Law.
https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg560251/#msg560251

However Inverse Square Law doesn't apply to Waveguides:

Below you have:
- point source  having spherical pattern of radiation
- line source    having cylindrical pattern of radiation

POLARIZATION

we continuing with  explaining polarization
however we need to  explain more about Standing wave
https://www.youtube.com/watch?v=hdCyA5eLCbo

_________________________________________________________________


Electromagnetic Wave in form of:
STANDING WAVE

 So far we  learned that:
 - our Tesla coil must be  vertically placed to the ground  and by that have vertical polarization to the earth/air INTERFACE.
   
earth/air INTERFACE is explained here:
   
https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg560166/#msg560166

 - between Top capacitor and Earth we have standing wave

   
standing wave https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg560291/#msg560291
   

Quote
The most common cause of standing waves is the phenomenon of resonance,
     in which standing waves occur inside a resonator due to interference between waves
     reflected back and forth at the resonator's resonant frequency .
     For waves of equal amplitude traveling in opposing directions, there is on average no
     net propagation of energy .

     standing waves

_________________________________________________________________

    The difference between standing wave and traveling wave is:
a- Traveling Waves transport energy from one area of space to another, whereas standing waves do not transport energy.
b.-points on a standing wave oscillate in phase, whereas on a traveling wave only points a wavelength apart oscillate in phase
    - the rest on that wavelength oscillate out of phase with the original point

c- Standing waves occur in confined spaces – in a microwave oven, on a violin string, or in Tesla coil between Top capacitor and  earth.(valid for  all types of SW)
    The waves interfere as they move about within the space to set up a series of nodes, or points of minimum vibration, and antinodes or
    points of maximum vibration. The most striking feature of standing waves is that they only occur for certain frequencies.

Quote
-Node (physics) A node is a point along a standing wave where the wave has minimum amplitude.
-Anti node- (physics) An anti node is the position of maximum displacement in a standing wave system.
 One characteristic of every standing wave pattern is that there are points along the medium that appear to be standing still.
 These points, sometimes described as points of no displacement, are referred to as nodes.
 There are other points along the medium that undergo vibrations between a large positive and large negative displacement.
 These are the points that undergo the maximum displacement during each vibrational cycle of the standing wave.
 In a sense, these points are the opposite of nodes, and so they are called antinodes.

The example of standing wave in transmission line is presented here:
https://www.youtube.com/watch?v=M1PgCOTDjvI
Transmission line : is any piece of wire  or conductive path  delivering signal to the radiating this wave element  like an antenna, or Tesla coil and that will be our load that  sends this energy OUT.
  e.g: generator sends signal  using transmission line ( wire. coax etc.) to an antenna.
 If impedance of that antenna  is matching impedance of  transmission line and impedance of  generator than we are able  efficiently
 to send its energy without standing wave  to an Antenna.

 We may also send energy of the generator to the resistor e.g 50 Ohm and dissipate  energy of  the generator without standing wave if  it matches
 the  impedance of the  transmission line and  impedance of  generator.   

 There is no dissipation of energy due to resistance in  ideal LC  circuits.

conclusion:

If we  want to send energy from point A to any point B we need:
- to have  energy from Generator delivered using transmission line to  the Tesla Coil
-we don't want any standing wave  be caused by impedance miss-match  of  generator and transmission line
 and if we had  no  standing wave in our antenna (Tesla Coil) this energy would be  taken by that antenna 
 and radiated into the free space around us. https://www.allaboutcircuits.com/textbook/alternating-current/chpt-14/characteristic-impedance/
 However  we don't want that either..


 We want  our energy from generator to be delivered to Tesla Coil and than we want to
 tilt  that energy by another means- (another form) of polarization .
 we don't want this energy  to go to the Far Field https://en.wikipedia.org/wiki/Near_and_far_field
 We want this energy to land at Complex Brewster Angle in the INTERFACE ( Earth/Air)
 And the magic word here is word COMPLEX.
 It's complex phenomena having Brewster  angle  as  one of its elements 



_________________________________________________________________


point source and line source is explained here:
https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg560319/#msg560319



So far we were talking about physical polarization of an antenna ( Tesla Coil)
Any vertical  to the ground  antenna  radiates  all around  and wave  spreads  horizontally in cylindrical pattern .
but because   the antenna is  vertical than  wave radiated from it will be  vertically polarized
So polarization of  the   electromagnetic wave depends from physical position of  our Tesla coil with reference to the ground .

Polarized electromagnetic wave :
polarization  of the wave represents how the electromagnetic waves are physically oriented in space.
