The crux of
the phenomenological problem is that power does not flow or move, nor is

But energy does flow and move and is something that can be reflected.
You can easily see the energy packets using a TDR. Without energy,
those pulses wouldn't exist. The energy is obviously in the pulse,
where the voltage and current are.

And joules of energy flowing past a point is joules/sec, i.e. power,
by IEEE definition.

Incidentally, how do you explain the Poynting Vector and the Power
Flow Vector?

The argument that fields "have" or "contain" energy is misdirected and
misapplied.


A lot of people will be surprised to discover that their electromagnetic
ExH and ExB values are "misdirected and misapplied".
