As far as RF is concerned, free electron particles indeed
do rest ON radiators. It's called "skin effect".

Cecil, After all this time of taking no decision who lost itat the
last minuite
Skin effect refers to current flow along the aluminum. It even shows
witness of this by inlaying circular grooves in its surface. This by
the way is a measurement tool in non destructive measurement. This
current method provides resistive impedance which signifies energy
lost. You then have another component which is termed radiation
resistance which points to energy applied to to create radiation by
the launching of the particles. When you do your fancy playing with
EZNEC you will notice that as the impedance goes down the radiation
increases. It will continue to do so while the impedance goes down as
a result of more current flowing outside the aluminum When you get to
the point when the impedance is zero it shows that all applied
current has been applied outside the aluminum which is now not
carrying ANY of the applied current. WOW!
You can also apply even more current of which all will still go to the
external sleeve of
particles to increase radiation and still no increase in current flow
in the surface of aluminum, even tho the impedance may go into the
negative quadrant. You also stated that applying a time varying field
is an example of typical failures! No idea where that comes from. Now
with reference to current flow in the particle sleeve. We had an
extensive discussion as to how the circuit of a half wave vertical
antenna was formed. At that time I was adamant that it must be a
closed circuit and suggested that return flow was thru the centre of
the antenna. Another brou har ensued with the implication was that
both the upward and downward travels of the applied current was on the
same skin deep surfaces! Very wierd. One of your past disagreements
with the group extended beyond the 1000 posts so I am certainly not
going to take on the debate mode with you.
Have a happy day.
