Radiant power from Solid state Tesla hairpin circuit

[evostars]

It works.
I made a half bridge circuit, from 2x2 series mosfets. This way the impulse voltage can be made much higher:

I've studied this patent, unfortunatelly not an easy text. The main goal is to produce a very dense magnetic field for scientific pourposes. It can be achieved with approprite dimensioned resonant coils.

Resonance can be presented in two ways:
A) The LC resonance, which means a periodic energy transfer bw. magnetic and dielectric fields, as we already know.     
B) As e.g. Don L. Smith sad too, the wire lenght must be calculated as a minimum of 1/4 wave lenght for a standing wave situation. The reflected waves cause in this case not a random shape (like an ocean surface) but a well definied large maximum at definied positions. This calculation takes the light of speed in account. So e.g. for 50kHz I calculate a wire lenght of 1500m (1.5km!). If I take a 10m wire, the frequency is 7.5 MHz. These are impractical values for a simple application.     

I'm not sure that an electric signal (not the electrons!) travels really with light speed in a real (RLC) conductor. Better say, the signal can travel with about 50-99% c, but the waveform what is created can change because of capacitive and inductive parts much-much slower. But ok, after a small amount of time we have a standing wave with a maximum.   

I must be honest, I can not imagine if I combine this two effect together what will be my benefit. How will be look such a magnetic field?

In some project of Don Smith, he mentioned that the important thing is only the relative wire lenght (1/4) of the primary and secoundary coil.
The reason for that it, it should be no unwanted back and forth signal coupling generated (causing an uncontrolled behavior becaouse of totally different wave shapes in the two coils).

Or what do you think?
