Now that I think more about that... I once did an experiment
with a plasma tube where the ion velocity is effected by the
electric field intensity. Made an quasi tem cell (lower
plasma angular frequency) where the cell mimics a parallel
plate capacitor, and connected to the plasma tube. Now the
circuit will act as a capacitor in parallel with an inductance,
and when voltage is applied at a certain frequency, the current
through C and through the plasma inductance are finite but
because the equal and opposite sign it becomes infinite at
the plasma angular frequency. The tube light up with 27Mhz
CB radio.. and when perfectly matched.. unkeyed and the tube
remained light!! The tube was in resonance with a very very
high voltage across the tube. It was the convection current
to the displacement current in the tube that was in oscillation.
There are a LOT of variables to the equation of stability and
resonance and deals with number of free electrons in the gas,
charge per ion or electron, permittivity of the gas and mass
of the gas or electrons. All in all was very interesting
experiment trying to match the plasma inductance to get it
stable.

PS.. not overunity though.. close but no cigar!
