In your above pulse example, there is no interference at

even exist. A Z0-match depends upon a steady-state supply
of RF waves.

A Z0-match at the input of a tuner works exactly like the
1/4WL thin-film anti-reflected glass coating. If one sends
a 1/2WL pulse of light at that piece of glass, there will
be reflections. Anti-reflective glass depends upon a
steady-state supply of light waves. One of the cancellation
components is 180 degrees older than the other one.

You really do need to choose your words a bit more carefully, Cecil.

Let's return to the Signal Generators equipped with Circulators
and Loads (SGCL). Would you agree that the feedline contains
300 joules in the following example?

200W SGCL----one second long lossless feedline----100W SGCL
200W-- --100W

Yes. But how much is there with the circulator load removed? (Not
replaced by an autotuner.) Numbers please.

Why you suppose I keep asking this question, Cecil?
