The fact is that the energy stored in a transmission line in the steady

power and the one way propagation time.

The time-averaged energy stored in a transmission line
doesn't vary with time (by definition) unless something
changes.

If the forward and reflected powers are based on fixed
RMS values of voltage and current with fixed sources and
loads, then certainly, time-averaged energy values can be
calculated. That's the nature of *irradiance* in optics
where instantaneous values are impossible to measure. The
Power Flow Vector is analogous to irradiance.

Is it all about semantics? Is the lack of a shared language the cause of
difficulty understanding your concepts.

No, the basic problem is that you keep accusing me of
saying something I never said. I have never used the
term "power wave" except in postings like this one.
I have no idea what is the definition of "power wave".

How it feels:

It feels to me like you are one of a number of people
willing to reject the basic principles of physics in
order to mount an argument with me or anyone else
who have been convinced by those laws of physics that
reflected energy waves exist in reality - you know,
the ones you actually see when looking in a mirror?
