Actually, it is more complicated than that. Since
the current impulse travels at the speed of light,
the current impulse energy transfer necessarily involves
photons. Note there is no current impulse traveling at
the speed of light under steady-state DC conditions
which is the only kind of current being carried 100% by
electrons. Any current, e.g. RF current, traveling at
the speed of light, involves photons, even the DC impulse
current.

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!

It is true that one can set EZNEC to lossless conditions but
one cannot do that in the real world. Aluminum and copper
are only ever lossless at superconductor temperatures.

Let me make myself quite clear on this point before the thread closes.
My position is that a radiator must be 1WL to achieve equilibrium.
When considering a
1/2 wave vertical one can only make it a closed circuit of 1 WL is by
adding a ground plane
rather than assuming that we have conflicting charge directions on the
surface of the 1/2 WL.
We now review the circuit (tank circuit) that applies to radiation. We
now accept that particles do rest on diamagnetic surfaces per the
Gauss extension. In fact, this surface or sleeve of particles is so
tightly formed that it has the hoop stress of a arbitrary boundary
such that nothing is removed from the diamagnetic material itself. In
the case where a particle is driven away from this border its place is
immediately taken up by one of the billions of particles floating
around looking for a diamagnetic place to rest.
We can now see that current applied to a radiating element splits into
two paths in parallel
One leg is in the intervening space between the particles and the
diamagnetic material and the other leg IN the surface of the
diamagnetic material called skin effect.
A computer program only recognizes the diamagnetic element such that
it only points to the impedance presented by that separate current
track .
Thus with increase in radiation the impedance referred to by the
computer is SOLELY
of that presented by the diamagnetic material. Thus when the program
states zero impedance it is stating that no current is being applied
to the diamagnetic material
and where all current is routed to the arbitrary boundary consisting
of tightly bound particles.
The concept of extreme cooling for zero resistance is not required
when no current is applied! All the current is now being carried by
the arbitrary border where all forces can be accounted for since there
are no losses incurred! Of-course the program itself leaves the
operator to sort this out because it did not supply a complete circle
of energy flow by ignoring the current applied to the particle sleeve
or boundary, where the energy lost in the
programs element is not supplanted with the energy gain of the
arbitrary border! This suggests that somewhere in the program the
positive and the minus signs were accidently interchanged. If the
programmer had recognised the existance of the Gaussian border
he would have the provided the means of energy transfer to it and thus
fully abided with the concept of equilibrium.
