Remember, the magnitude of energy in a transmission line
is *EXACTLY* the amount of energy needed to support
the forward joules/sec and the reflected joules/sec.

If you go beyond your (unqualified) average view of the world and
drilled down on the fields in the line as a function of time and
position, and their relationship with steady state real and reactive
energy flow at each end of the line in the general case, it may
provide you with a more correct view of the tranmission line and its
load and source in your favoured energy context.

I have done that, Owen, and let's see if your experience is
different from mine. Please go to the following Florida State
University web page:

Cecil, I am talking about the way in the steady state in which energy is
stored in E and H fields within the transmission line when standing waves
exist, and the way in which energy is exchanged between E and H fields
within the line, and the load and the source at each end of the line, and
the net energy flow averaged over time (power).

Your analysis of energy waves or power waves doesn't give you the
information to see that level of detail.

Whatever level of detail one chooses, the energy
in the forward waves plus the energy in the reflected
waves will equal the total energy in the transmission
line which will always be the energy sourced and not
delivered to the load (in a lossless system). This
will be true right down to the last photon.

Unless someone can prove that EM energy is
transformed into some other form of energy for
storage in the transmission line and then transformed
back to EM energy when the transmission line is
emptied, the nature of EM energy and the conservation
of energy principle dictate what happens. EM (photonic)
wave energy cannot move at less than the speed of
light (modified by VF).
