From "Reflections", by Walter Maxwell, 1st edition
Sec 4.3:

"The destructive interference causes mutual cancellation
of two complementary reflected waves ... Wave interference
between these two complementary waves ... causes a
cancellation of energy flow in the direction toward the
generator."

In the context that I am using the words, either
"superposition" or "interference" could be used. They
are two sides of the same coin.
