None of those observations proves the existence of "waves of energy and

Ian, I haven't seen you, or anyone else, offer proof that
"waves of voltage and/or current" can exist without energy.
I always thought ExH equals the power in the Poynting Vector
for any EM wave whether it be an RF wave or a light wave.

The world is still waiting for an explanation of the detailed internal
workings of *any* of those devices, done entirely in terms of "waves of
energy and power". A newsgroup limited to ASCII text is not the best
medium to attempt this... so will the forthcoming QEX article oblige?

The QEX article's present title is: "An Energy Analysis at
an Impedance Discontinuity in an RF Transmission Line".
It is mostly a review of the principles of the wave
reflection model which was invented before anyone hatched
the stupid idea that waves can exist without energy. :-)
It will be mostly old hat stuff for people who have ever
done an analysis using power reflection coefficients but
that seems to be a lost art lately.

Incidentally, a complete analysis of a Z0-matched impedance
discontinuity can be done using only an energy analysis.
If voltages and currents are actually required, their
magnitudes and phases can be calculated from the energy
components.
