Please give us the equation for "ordinary AC voltage or current".

No argument. But a standing wave still represents storage of energy in
the line, as with any resonant structure, and that stored energy shows
up as magnetic fields and electric fields along the line. The big
difference is that the magnetic fields bob up and down at some areas and
the electric fields bob up and down half way in between those areas. At
any given moment, there is a fixed total energy in the combination of
all the magnetic and electric fields.

No argument, and therefore no need for the "But" in your statement.
I agree with you but it doesn't change a thing about the real
argument.

Exactly. How can you write this, but deny the capacitive current that
delivers this electric field energy twice every cycle to all capacitance
feeling this voltage swing?

I don't deny it - never have - never will. Please stop trying
to set up straw men. The discussion has *NEVER* be about what
happens during one cycle. The current measured by W8JI and W7EL
and reported by EZNEC is RMS current. Instantaneous values are
just another straw man diversion.

Profiles do not charge capacitance, ...

I'm glad you agree. Profiles are maximum RMS envelope values
and that is what EZNEC reports.

[Standing wave phase] "doesn't rotate at all, and the resultant
wave it represents doesn't progress through space - its a standing
wave."

I suggest you drop talking about phasors, till you understand what cos(wt).

Hecht and I have been a little lose with words while assuming
the readers have a certain knowledge level. For the uninitiated,
When Hecht (or I) say the phasor doesn't rotate at all, we
mean the phasor doesn't rotate at all with respect to the
source phasor. Any initiated person would know that. The phase
of the standing waves doesn't change with respect to the phase
of the source signal. Hecht assumed you would know what he meant
by that statement.

Speaking of "... net transfer of energy, for the pure standing
wave there is none."

A standing wave does not violate conservation of energy.

Exactly my point! Nothing violates conservation of energy. If
the RMS forward current in the coil is the same magnitude at
both ends and the RMS reflected current in the coil is the
same at both ends, the conservation of energy principle is
satisfied NO MATTER WHAT THE STANDING WAVE CURRENT TURNS
OUT TO BE. What is it about that statement that you don't
understand?

Storage that must continuously be swapping back and forth from magnetic
field energy to electric field energy. When the energy storage is all
electric, that implies charges capacitance.

Again, nobody has ever been discussing what happens within a
partial cycle. Discussion of such is obviously a diversionary
straw man. Feel free to find someone else willing to discuss it.
It is completely irrelevant to this discussion of RMS envelope
values.
