Title:
Wireless Energy Harvesting by Direct Voltage Multiplication on Lateral Waves From a Suspended Dielectric Layer

 Link: https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=8053760


From  part  #1  we have learned   that
-earth as    multilayered part of interface  is suggested.
-that is  in line  with Marconi’s early experiments,
-the paper explores the feasibility of wireless energy harvesting by direct voltage multiplication on lateral waves.
-we could also look at  picture  representing multilayered  interface
-  we  had the first look at wave behavior while  "loading" into  interface

From  part  #2  we have learned:
- the  differences  between  regular EM wave known also as Space wave and Surface wave.
- the 4 layer suggested   ground  as one of parts of interface Air/Earth
- the wave  in  the  interface  must  be  in TM  mode

From  part  #3  we have learned:
-  that  the thickness of both layers  of the  interface is expected  to be 1/4 of  the  wavelength Y

From  part  #4  we have learned:
Basic schematic   of  Avramenko fork and  voltage multiplier   that can be used at any frequency
in association with Goubau line or any other type of interface.

From  part  #5  we have learned:
 SIMULATED AND MEASURED RESULTS OF BASIC WPT (Wireless Power Transmission)CONFIGURATION
We can see from Fig.3b Fig.3c impressive performance   of TM in the interface.
=======================================================
Quote
lateral waves can significantly increase the energy efficiency due to less signal attenuation compared with space waves, therefore,
WPT based on lateral waves can be used for simultaneous charging of the sensor nodes more efficiently
without causing harmful interference to wireless communications.
-this above is another confirmation of expected performance over the regular  EM wave

Quote
In addition to inherent nature of lateral waves for interference reduction, the delivered power by lateral waves canalso
be conveyed on a lower frequency channel
.
Quote
The power can be preferably delivered at a lower frequency,say at any frequency below 500 MHz, where a highly con-centrated lateral wave is easier to form.
-this above is another confirmation of expected performance TM  in the interface at low frequencies.

Quote
delivered power does not impose any interference to the received signal, the energy to be processed by the receiver
at the receiving end can be pre-filtered with a high pass filter. Fig. 5 illustrates this scenario.
-this above is another confirmation of fact that this wave is not  present in Far Field 
The exact  statement  saying  it  is int the article I just must have time to find it

Summary from all 6 parts:
I did not yet write  it. 
Just  lack of time
but in overall it  kills most if not all of  the skepticism

Im just looking for some suggestions.

I have in my possession   EIN model 500L .
After reading some posts i find recommendations to use EIN 3200L $$$$$ :( .
 https://overunity.com/17735/wesleys-kapanadze-and-other-fe-discussion-forum/msg536259/#msg536259
For now ill try to stick to Tesla coil concept and not corums polyphase probe type of structure. ( Unless 500L can be used successfully )
My amp is very low power some 300mW and i wonder if this can be used to switch a transistor 2SC5200  for example.
It should be good for 2-500 mhz but i see a lot of distortion at higher frequency, maybe poor cables.
The goal  is to use signal generator ( variable frequency ) to power a solid state tesla coil in simple way. (2-3 Mhz)
kind of like slayer exciter but variable frequency. 
Any schematics?
Thank you for all the help.

It can only be used as preamp.
You need significant power.
But Ham radio TS-2000 can be used at its low 1.8MHz.The prestige Transceiver .
or any other Transceiver.Some of them can be on Ebay for less than $100 or go to Hamfest
Be careful as you at first need to use it at CW short impulses like from electronic Morse Keyer and let it rest.
You may damage it at no time due to  impedance mismatch

SWR meter is needed to most of them.
Note:  use of these transceivers requires FCC license.But you have rights to own it . :)

Why do you need a power amplifier? Each tesla coil is your amplifier and transmitter. As a last resort, you can use the music version of the tesla coil!

That  depends from  what  is your  application.
If you want to send energy  from point  A to  point  B at some distance  than
due to impedance  mismatch it is easy  to  lose  these 300mW
Your signal generator by  itself may  have that power level  of  power  at its  output as  well ....so  what do  you need  the  500 series amplifier for?
In any other case your generator can be  connected to any external  amplifier having much bigger  power at desired frequency and is available on Ebay.

Each tesla coil is your amplifier and transmitter.
NO   IT IS NOT.
Tesla  coil  is  only changing   voltage   from  low to higher but power level is  never amplified.!!
If you deliver  300MmW to  Tesla coil primary at 1V    where  primary  is 1 wind and  secondary  is 1000  winds  than you will get at secondary  1000V
but overall power will  be 300mW    minus  the  losses.  !!!
Using terminology -  "Voltage amplification"  may  be  not   quite  accurate. 
You  amplifying nothing
You just losing

Basic rule is:
-  The  power at input is always bigger than  power at   output!!!
so  Tesla Coil  as air  coupled  transformer can  be  called "LOSER"
as opposite to "gainer"

In regards to  Tesla Coil being called Transmitter?
Yes it transmits    something....
but that depends from   application
No it
does  not transmit/ doesn't radiate  in  Far filed ....but that depends from   application

The basis of the principle of signal transmission is to generate an RF signal which is a high frequency electromagnetic wave, so why do you think that the Tesla coil itself is not an amplifier, let alone a transmitter? It amplifies by increasing the amplitude or is that not what the amplifiers are about?

what the amplifiers are about?


Amplifier:
Quote
electronic device that can increase the power of a signal (a time-varying voltage or current)
https://en.wikipedia.org/wiki/Amplifier
Tesla  Coil is never amplifying  power of signal.

Amplification  of  power must be seen  as  done at cost of  someone who is  giving you needed  energy for it.
(and  that can be  your   own pocket when you pay the bill  for electricity)
the  very concept of free energy is to  find this someone who pays  for it and than  you  pay nothing.
e.g wind,  solar,  thermal, or energy from Schumann waveguide

This is obvious but I don't think we've understood each other about the word amplifier.
I meant an amplifier in the sense of a power amplifier, e.g. for a music.

Condenser: A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store energy electrostatically in an electric field.

In the past, the Condenser was also know to be an active component condensing or concentrating an electric fluid. In fact one can still use a wire antenna, condenser, inductor and a rectifier to condense electrical atmospheric energy. Some say this is just a receiver for Hertzian waves however it is also known in the art to be able to condense or concentrate electrical energy like an amplifier. However in the case of the condenser we are not amplifying an Electro-Magnetic signal but separating and concentrating electrical charges as energy.

Passive components are well enough however the real action is in active or dynamic components.

It is  the same for every  amplifier-  the same rules apply.

Cytat z Wiki
Most modern audio amplifiers have a flat frequency response as shown above over the whole audio range of frequencies from 20 Hz to 20 kHz. This range of frequencies, for an audio amplifier is called its Bandwidth, (BW) and is primarily determined by the frequency response of the circuit.

Wlasnie sprawdzilem jak wyglada uzycie Wzmacaniacza audio Blaupunkt  PCA2120 2x120W 1x300W.
Podlaczylem generator sygnalow i uzylem wylacznie pozytywnej czesci pulsu sinusoidalnego niebedac pewnym czy
to cos dziala na sygnal przemienny czy tez tylko staly w postaci impulsow ( az tyle to nie wiem a szkoda mi tego wzmacniacza, moze w
nastepnym aucie mi pogra jeszcze :) )
Na wyjsciu oscyloskop pokazywal sygnal sinusoidalny a wiec to by moglo calkiem niezle dzialac przy 13-14volt i jakies 10 amper.
Niestety zgodnie z informacjami o wzmacniaczach audio wraz ze wzrostem czestotliwosci tracisz tzw GAIN. Jego mozliwosci wzmocnienia sygnalu znacznie  spadaja powyzej 120khz . A wiec wyciagajac wnioski moge spekulowac ze daloby sie zrobic Tesla coil na podobienstwo Slayer Exciter i kontrolowac czestotliwosc ale tylko na duzym lub bardzo duzym transformatorze ktory ma swoja czestotliwosc rezonansowa
w granicach 100khz i ponizej.
Wlasnie dlatego szukam mozliwosci podlaczenia generatora sygnalow do wzmacniacza ktory bedzie pracowac satysfakcjonujaco w przedziale czestotliwosci radiowych aby transformator Tesli nie byl duzy oraz latwy do zbudowania i szybkiej modyfikacji w razie potrzeby.
Dziekuje za pomysl i pozdrawiam

Luc,

Allow me to ask this:

- Will your power transmission work without the top load capacitors in place?

- If the top terminal is one plate of a capacitor, where or what is the second plate?

- How do capacitors work?

Okay poynt99

Both Tesla Coil top load capacitors are removed and circuit still delivers 7 watts through the single wire to Rx 50 feet away and even outside the concrete block building that Tx is located in.

The power transfer efficiency is not as good since I had to use a lower resonance point of 150kHz for stability compared to 230kHz originally demonstrated.
Without the top capacitance the ideal resonating frequency is much higher, difficult to tune and I fried a few mosfet's trying to get it.
So I had to settle with 150kHz. However, it still should be fine to prove the point that the circuit has not been using the top caps to complete the current path.
So how is it completing the current path?

Luc

Going back to single wire power transmission .
I apologize for messy drawing. Thinking about this experiment https://overunity.com/17735/wesleys-kapanadze-and-other-fe-discussion-forum/msg537420/#msg537420 i wondered if its equivalent to placing a capacitor at the bottom of tesla coil and
connecting earth end of a coil to one plate of  capacitor and single conductor to other, same for Tx and Rx . I did just that with random capacitors and its working like capacitor was
not there, makes no difference. I took no measurements just tried it.
So whats the point:
since this work should lead to power transfer via earth and so called interface - surface wave, i doubt that single wire ( metallic conductor )
will lead YOU anywhere close to your goal. Im not a skeptic and i did read about plans and ideas of using surface wave to send and receive signal between airplanes sensors and main computers on outer shell and wings (mam na mysli aluminiowe  poszycie samolotu ale nie wiem jak to nazwac po angielsku) in order to save money on wiring and weight of a plane itself and i totally agree it will work but for engineers with proper know how, understanding and state of the art equipment . So the wave exited by Tx bounces back and fort and gets utilized in Rx some 40 or 70feet apart might be easily mistaken by a surface wave and give you false assumptions.  Its just an opinion and i wonder what Wesley can say about my drawing.
Thank You

It is  absolutely lifting me up that I have so big Polish  participation in here.
And it is not because of Marie Skłodowska Curie
https://en.wikipedia.org/wiki/Marie_Curie

My wife is Psychologist  she was born in Poland  and she got one of the best level of education possible.
There is something unique about these folks.
Something that made them different among many nations around.
Fighting  for so many centuries with Russian Aggressor they developed  need of being better and better in everything.

Simple and short:
You put them at any place and any country,without
knowledge of language, green card, and zero money  in the pocket
-dentist can become successful and wealthy construction guy in just 15-20 years from 15 dollars in his pocket  when he landed in Kennedy airport.
-surgeon will become  successful banker
-and microbiology student can become respected professor in famous  American university

Typically it was 6 to 10 years for most  of them to buy their first house in USA
Besides of Tadeusz Kosciuszko and Pulawski being heroes of American history.
https://en.wikipedia.org/wiki/Tadeusz_Ko%C5%9Bciuszko
https://en.wikipedia.org/wiki/Casimir_Pulaski
I could simply say that just because of skills of these folks fighting with Russian aggression 
their escape  to America  - America got its independence under their command .
Today (Wednesday) is my holiday
And today I as an American express to you my Polish friends  my respect to everything you value.

Uniqueness of Polish Education System .
In 1950-2010 they had to learn approximately 300% more than average American in areas that have
been not so much included or just only "mentioned" in American school system
So their overall education  was very broad and not so much specific .
This was good and bad.
But becomes a precocious (exhibiting unique  qualities)  to/by any one who had to run for life from Poland  from
Russian oppression especially in  20tieth  century.
For these who don't know it was Poland who made possible  :
-fall of Berlin Wall
-freedom  of several countries from Russian/Soviet terror 
- fall of Soviet Union  starting from 1980 to 1991
https://www.britannica.com/biography/Lech-Walesa
So what do we need this information for?

Polish are quiet, peaceful pushers of everything around.
I'm pointing at enormous and very uncommon ability to adapt to any possible conditions of life.
This is their uniqueness
- Great educated nation of quality people.
-Poland as leading economy in EU (GDP ) looks like sweet beautiful clean, modern candy - she shines  with her beauty.
-Poland is not chap like some of other Eastern European countries but you'll get what you paying for.

And I happened to be very much oriented in all of the aspects of that part of the world.
I understand all of 27 Slavic languages,
I speak 3 of them fluently
And two of them absolutely perfect... well..only  after few days  of being there..
