In the s-parameter equation, b1 = s11(a1) + s12(a2) = 0,
the interaction of s11(a1) and s12(a2) results in wave
cancellation. The effect of each wave on the other is
to reverse the direction and momentum of both waves.

That is what happens at a Z0-match in a transmission
line. That is what happens at the surface of thin-
film when reflections are being canceled.

Again, the redistribution of the wave energy is certainly
an interaction that wouldn't exist with either wave alone.

Redistribution is an interaction....interesting. But, you were
telling us about how waves interact with other waves. I'm interested
to know what effect x has on y, and vice versa? We have x + y making
z. So after that, tell us how have x and y changed as a result of
their "interaction"?
