Where Does the Power Go?

That's looking forward into a Z0-match from the source
side. The opposite thing happens looking back into a
Z0-match from the load side. What's the opposite of
an anti-reflection?
Actually, in my energy analysis article, I defined
the word, "re-reflection", as used in the article
and as used by Walter Maxwell in "Reflections".
Cecil,
Where you go wrong is your energy analysis. Your argument goes awry
in at least a couple of areas. 1. 'destructive interference causes
energy to reverse direction.' This is purely false. Interference is
the description we give to the result of the superposition of waves.
It is not a causal phenomenon. 2. Unless you're talking photochromic
properties, partially reflective media interfaces do not become 100%
reflective in response to illumination (or for any other reason). Any
"re-reflection" that takes place is ordinary partial reflection in the
other direction.
Have fun on the hog. Last weekend I was fortunate enough to drive 20
laps on a 1/2 mile banked track in a Busch class stock car. Holy cow.
