@newssvr14.news.prodigy.net:

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.
