Cecil's circulator is a device that gets hot when reflected
waves are present, proving that reflected waves possess
energy and power.

Cecil's TDR allows everything about a reflected pulse to
be known and measured.

Cecil's TV ghosting allows one to see the reflections with
one's own eyes.


None of those observations proves the existence of "waves of energy and
power". They can all be explained more simply and easily in terms of
waves of voltage and/or current (or in circulators and waveguide, waves
of E-field and/or H-field).

The world is still waiting for an explanation of the detailed internal
workings of *any* of those devices, done entirely in terms of "waves of
energy and power". A newsgroup limited to ASCII text is not the best
medium to attempt this... so will the forthcoming QEX article oblige?



I'm a professional teacher

Then this is far more serious than I thought! :-)
