But you're missing, or trying to circumvent, the most interesting aspect
of the problem. It's the one which highlights the very core of our
disagreement. The energy stored in the line, remains stored in the line
as long as steady state is maintained without a single Joule of
additional energy moving into or out of the line. To me, this
illustrates clearly how the fields at the impedance interfaces of a
matching transformer can be maintained without requiring multiple
rereflections of energy. I'm hoping some day you'll see it too.


You are, of course, talking about NET energy, and I agree with you about net
energy. But it is easy to prove we are NOT dealing with net energy by
observing
ghosting on a TV signal. It is easy to prove that multiple re-reflections
are
indeed actually occurring in reality.

Your argument is that if 5000 cars cross the bridge into the city during the
day
and 4990 cars cross the bridge out of the city during that day, that only 10
net cars have crossed the bridge in a day. I agree with your net figure but
note that the bridge cannot be replaced with a 1 car ferry boat operating
tens times per day which is akin to your above argument.
