I understand the movement of charge within a cycle, Gene. But
it is irrelevant to the discussion and just another one of
your strawmen erected as a diversion away from the relevant
issues. Why do you think such a transparent diversion
would work?
During a cycle, energy is obviously exchanged between the
E-fields and H-fields. For a 1/4WL antenna, that means
migration from end to end. But everything being discussed
so far are RMS values. EZNEC reports and displays RMS values
of current. All of the measurements reported so far were
RMS values.
There is no net storage of energy in the coil based on the
product of the RMS voltage and the RMS current. Everything
about RMS standing wave current can be understood simply by
superposing the RMS values of forward and reflected current.
func(kx+wt) + func(kx-wt) = func(kx) * func(wt)
You were the one who posted that information. I don't
think you quite realized what a boost that was for the
distributed network model. The lumped circuit model has
no provisions for accomodating the above equation and
presupposes faster than light propagation.
Your next logical diversion will probably be - trying to track
the position and velocity of an individual electron in an
antenna. :-)
