Default Constructive interference in radiowave propagation

I fully understand it Jim. I'm willing to take the time
to explain it to you with s-parameter examples, but you
have refused to listen. One wonders what you are afraid
of and what you have to lose except face.

Where there are waves, there is energy. Where there are no waves, there
is no energy. Show me the canceled waves.


b1 = s11(a1) + s12(a2) = 0

s11(a1) and s12(a2) are the two waves that are being
canceled. They exist sum to zero. Have you ever done
any phasor or vector addition?
