Default antenna physics question


Hi ...

I am let to chime in, but I would really like to take part in the
discussions.

Aurthur, I am a student of physics. The way I understand the situation
is as follows:

There is no charge moving. In practice, nothing is moving. an EM
(strictly E) field is created, into which power is distributed. So if
you pump more power after some saturation, the medium will breakdown to
provide an alternative mode of transport, i.e. direct conduction in this
case


Therefore i would appreciate if you elaborate what you mean by
trajectory of the charge.

I have been struggling with this for some time
so maybe somebody can set me straight.
We wind a flat plate spiral antenna and we get to a point where the
center medium becomes saturated with flux.
Now I add even more coils. What action does that precipitate? I would
like to think that the Meissner effect ( perfect diamagnetism) then
takes over and swamps the external magnetic field as with a
superconductor ( ie opposite to that of a paramagnetic) The skin
effect is thus removed allowing the current flow to the surface by
allowing the atomic structure to relax, and add to the current already
in place to allow fully efficient radiation as it now lies outside the
confines of conductor resistance.
This is my effort in determining what is it that drives the constant
impedance attributes of a meander type array?
