Of course, I am always open to "new proof" (heck, even old proof will do!)

However, in a capacitor, I do believe that power and/or current does
travel the surface of the plate(s.) *

But of course John it will travel along the plate
that is natures way of seeking the point of least resistance
to cross. Remember that the plate of a capacitor represents an
inductor which in combination with a capacitor has the same
constituents as a
tank circuit except that it is not being subject to a time varying
field.
I would like to say that I was in error stating that the when
programers made the computor program
on antennas on the premise of a contunuous sine wave they are quite
correct when viwing it from yhe stand point of a
tank circuit.





To make a jump from this
acceptance, to one accepting the same occurs at rf, where a signal
actually leaves the antenna and enters/"rides"/travels/propagates the
ether, is easily made, at least by me.

I think the case is slightly different, it needs a continued varied
current to
achieve a stable eddy current which gives the ability for levitated
charge movement
and in the capacitor case the point of least resistance is pre
established after the first varient in current
and it is the current movement inconjunction with the eddy current
that provides the essential spin needed
for inline projection




Since, obviously, the signal MUST leave the surface, why not just travel
it (shortest distance between two points--and all that) to begin with?


Exactly . After the first pulse of current flow the point of least
resistance
is attained so yes the charge will travel at that specific point.
When a capacitor breaks down you cannot see the path taken by the
current
on the initiating plate but you can see a point trace where the charge
impinges
on the reeiving plate as opposed to the whole area of the plate.
Remember convention if correct states that a capacitor does not
radiate

I do believe it does travel the surface, if at all possible; *however,
given a very thin radiator and/or a very large PA, it would not surprise
me if you can't force the current/power/VA to another route ...


I don't see how that could happen except when a charge is released it
produces a
lesser resistance route by ironizing of the medium travelled either in
the initial case
or of a resultant discharge travelling thu ozone.
