Malcolm,
I specified in my post that the driver is not continuous wave, but fast
rising pulses with information content (read harmonics) and relatively
long periods of quiessence between pulses. The vacuum tubes or IGBTs
are driven electronically and not by feed back from the resonator.
Dr. R.
What is the configuration of your primary circuit without the secondary
that drives the magnifier resonator? Is it continous wave or
disruptive? How is your magnifier resonator grounded?
