Tom,
May I point out that a Tesla coil is an "antenna" that does not
conform
to Maxwells laws with respect to the adherance to the LC ratio.
The LC ratio is out of balance such that the capacitor is not
of the correct size to store and then return the imposed energy from
the inductive heavy coil which is visually seen as resulting in a
spark.

Huh...

tesla coils follow all of Maxwells equations quite nicely. Paul
Nicholson did some very nice analysis on this a few years back,
published at a link previously posted.

They're two coupled LC resonant circuits, with the coupling adjusted to
around k=0.2. There are higher order systems with 3 or more resonators,
as well (called Magnifiers in the TC world)

The challenge in spark making is choosing appropriate operating
parameters (coupling, radius of curvature, topload capacitance, etc.) to
optimally promote spark growth.

Let me make it quite clear. I was referring to a single coil and
not the feeding arrangement. I used that as a refernce only in
conjunction
with the subject of antenna coils. This single coil, tho resonant,
does
not meet the requirements that Maxwell demands ie equilibrium.
Further study of that coil will show the effect of ground beyond the
coil
which thus involves the system as well as the associated coil for feed
coupling.

But you made the straightforward statement: "Tesla coils do not conform to
Maxwell's laws", thus opening the door to a new field of study in
Electromagnetics. In fact, if you could look into this a little deeper,
you may in fact be the first person to unify field theory (something
Albert Einstein himself failed to do). This may be related to the success
of the Philadelphia Experiment.
I think you are on to something here :-)

That would appear to be a partial quote from the sentence and implies a
completely different meaning from what was stated. I interpreted the
statement to mean that Tesla coils exhibit extreme LC ratios which are
outside the ranges that have been found to be most efficient in resonant
circuits for radio communication. (As established by Maxwell and others from
experimentation.)

A resonant circuit for any given frequency can be made up using a capacitor
and inductance of any suitable values. Using very a very large capacitor and
a small inductor, or a large inductor and small capacitance may well work
very well in a given situation, but experience has shown that selecting
components with median values results in more stable and efficient circuit
operation.

Tesla coils form very sharply tuned circuits with some quite extreme
component values and voltage levels. Their operating parameters do tend to
lie outside what is considered 'normal' for amateur radio.

The Philadelphia Experiment was a success? Why didn't anybody tell me? What
time did the ship get back?
