There are 2 kinds of resonance.
One is the normal known, a resonance between the dielectric and magnetic field energy in a coil.
The second one is different. it is also based on dielectric resonance. but its counter part isnt the well known magnetic field.
Its a different kind of field, that has no magnetic properties.
Resonance is the transformation from one energy form into another, and back and forth. just like a swing.
The sine wave of the dielectric field (measured in voltage) can be measured easily with a scope. when the voltage becomes zero, it means the dielectric field energy is zero, so it has been transformed 100% into the magnetic field energy, in the first kind of resonance.
The magnetic field can also be seen and measured. With a gauss meter, or simply by a compass, near the coil. It will deviate, when at resonance.
But in the second kind of resonance the needle doesnt deviate, and the gauss meter is not measuring a magnetic field strength.
But, the voltage does become zero. the energy can't just disappear and reappear. So there must be a 3rd kind of field, where it is resonating with.
I see the dielectic field, as ropes of twisted eather, between the windings of a coil (capacitance).
A magnetic field, I see as a Aether vortex.
The third field, I think is like a ring vortex (like dolphins blow vortex rings).
The magnetic field, and the 3rd field, look almost the same.
the magnetic vortex, twists inside in a spiral.
The 3rd field ring vortex twists inside as a circle.
How, to create the 2 kinds of resonance?
I use pancake bifilar coils, series connected, because they have increased capacitance, en therefor can store more energy in their dielectric fields. This makes the resonant frequency of the coil lower.
The first resonance, is created by using 2 of these pancake coils, stacked in parallel.
One is pulsed with dc, and the other is grounded at one side, and probed at the other side. this coil is resonant, if the frequency of the pulses is at the resonant frequency of the resonant coil.
The second resonance, is created differently.
I still use the same two (biPHIlar) coils. But now they are separated. (so the first resonance doesn't happen).
The first coil is still pulsed at the resonant frequency of the resonant frequency of the second coil.
But now, we use the back emf, created by the collapse of the magnetic field of the first coil, when the pulse is going to zero.
This Back emf, voltage spike, is fed into the second coil via a diode.
Now the resonance is different. now there still is the voltage, but the magnetic field isnt detected anymore.
I think it is, because it is hit like a hammer on a bell. The back emf spike, is direct instant energy. resulting in a ring vortex.
Just like sound is longitudinal. the ring vortex created, represents a longitudinal field.
To increase the back emf pulse, I increase the inductance of the coil, by adding MnZn ferrite.
I also increase the current into the first coil.
And I increase the duration of the pulse, by using a depletion mode mosfet.
This d-type mosfet passes current, when no signal is applied.
The signal I use to interrupt the current, is another back emf, at the gate of the mosfet.
This quickly turns the mosfet off and on again.
This makes it possible, to combine BOTH resonances in the second coil (when it is placed in parallel with the first coil)
