Lets make sure I follow, You are saying that radio communication
occurs because and antenna emits statically charged particle that
then
imparts their charge to the receiving antenna when they strike the
antenna. Is this what you are saying.
Yes. But in form of longitudinal waves. Electrons go out and come back
from
the end of radiator. For this reason he can wrote: "the idea of point
radiation which leads to efficient small volume antennas.
And following these edicts I have been able to make radiators of a
smnaller volume that is known in the present state of the art."
When electrons oscillate in a transmitter the voltage at the end of a
radiator is doubled and the strong Gauss electric field is produced.
Such
waves are longitudinal.
Exactly which particles are you saying are responsible for this?.
Here are many hypothesis. One of them is the Diracs electron see. So
the
electrons in the conductor kick the electrons in the space. But it is
not
important. Radio people should know which part of the radiator radiate
and
what the waves a normal pressure waves or artifical TEM waves.
S*
so how do antennas encased in insulators work at all?
For this Maxwell invented the displacement current. It is oscillating
current in insulators. In insulators are charges which can not flow bat
only
can oscillate. They can oscillate to and fro and/or rotate about some
angle.
....
Hmmm. Are you suggesting that there is no displacement current in a
capacitance that uses a vacuum for dielectric?
Yes. But it is not suggestion. The displacement current is necessary for the
incompressible electricity.
Now we know that the voltage is doubled ( Marx high voltage generator) and
that means that the electron gas is compressible.
The dielectric between capacitor plates undergos the electrostriction.
Sigh. I'm glad I didn't have to learn E&M from reading r.r.a.a.
But it is interesting to look at Maxwell's drawings to his model of the
vortex see with the idle gear.
