Cecil,

The waves you are so worried about are merely convenient, but
fictitious, adjuncts to your mathematical model.

You need worry only about the energy of real, measurable waves, not
those adjuncts that simplify the math.

The use of such adjuncts is done frequently in solving real problems.
Just don't confuse the internals of the model with physical reality.

Might this be an example, Gene?

From "An Energy Analysis at an Impedance Discontinuity in an RF
Transmission Line, Part I"

"100% wave cancellation means 100% energy reflection."
