You have made that assertion so many times it has turned into a Big Lie.
Maybe you should reveal the agenda responsible for such unethical behavoir?
What I have said is that the *energy* involved in destructive interference
at a Z0-match point reverses direction. The waves are *destroyed* by the
destructive interference and the waves therefore cease to exist. So how could
destroyed waves possibly reverse direction? They cannot! Your assertions are
simply false. Perhaps you are confusing the energy in the cancelled (destroyed)
waves with the waves themselves? In any case, unless I accidentally mis-spoke
sometime, I have never said that cancelled waves reverse themselves. To say
that cancelled waves reverse themselves would be a ridiculous assertion.
The *energy* in the destroyed waves cannot be destroyed and we know that it
doesn't continue on toward the source. Therefore, the *energy* in the
destroyed waves changes directions and becomes constructive interference
flowing toward the load.
The *energy* in the cancelled (destroyed) reflected waves reverses directions
at the Z0-match. There is simply no other possibility since reflected energy
toward the source is eliminated by wave cancellation. All this is explained
on the Melles-Groit web page if you desire to comprehend. They say the "lost"
reflected energy is not lost at all and enhances the forward wave. How can
reflected energy enhance the forward wave without changing directions?
