The model which I described envisions an unbalanced charge present in
decayinterior of a uniform conductor at t=0, and predicts an exponential
length,of the charge at that point - with a time constant of
epsilon/conductivity.
The derivation is not complex and is in almost any Junior E/M text.

I had better pursue this one - the concept is important to
intending engineers.
If the initials following Bob's signature represent his amateur
radio interest, then I expect he will have no dificulty in describing
the time progression of a shock excited end fed dipole of 1 meter
and say 5 mm diameter.resonates
For non enthusiasts, I am describing a high Q structure that
near 150 MHz for numerous cycles after a shock impulse on one end.antenna
Military sites that need more bandwidth capability from a dipole
replace the slender wire first with lower length/diameter conductors,or if
necessary with two cones, base to base. The Q is reduced, and thebandwidth
increased.bandwidth.
The conductive sphere is a limiting case of this design variation.
You expect resonant frequency lowering, very low Q and wide
nanoseconds
The side to side electrical field effects are certainly in the
timescale so if Bob cares to cite an elementary E/M text which appearsto
show superluminal effects on the timescale he mentions, I expect I will
be able to point out the appropriate interpretation.
