Hello. From my experience it is clear that there are longitudinal waves, so there is longitudinal resonance in any coil with or without a magnetic core. It is different from the resonance of L C. Anyone who plays with frequencies lower than 1Mhz can discover it. Quantum physics and quantum mechanics do not exist and are the inventions of frustrated scientists that the universe in which they live does not match reality. Another invented word that saves ignorance is: big bang.

Series Mosfet switching, for high voltage impulses Videos
« Reply #1606 on: January 30, 2021, 12:39:34 PM »
I made 2 new videos, they show the series mosfets switching together, using a basic Radiant power circuit (2019 april),
 This makes it possible to create high voltage (3500V) impulses, from coil discharges, using 2 1200V SiC mosfets in series switched.

This video explains the idea of mosfet switching, and the Tesla oscillator article is explained:

This new video  of me, shows the series mosfets switching:

Multiple mosfets could be used, but the bottle neck would probably be the isolated gate driver (which could be a optocoupler with glass fiber)
, and the isolated dc dc converter (which could be a battery).
I tried using 1700V mosfets, but their pinout was wrong.
The c3m1200V mosfets are on order but should be available later this year.

Many think Tesla only used capacitor discharge current impulses, by making use of quenched sparkgaps,
.but he used coil discharges in his later years of research, to create voltage impulses

My idea still is to use a dual primary setup, one for dielectric induction (use the pancake coils as capacitor plates), the other for magnetic induction

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