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.) 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.

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

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 ...
