Except that power and energy, like mass and time, aren't things which
'cancel'. Fields on the other hand can superpose, interfere, and cancel.
You're still presenting that straw man riding that dead horse.
Please read my lips, Jim. *ENERGY CANNOT BE CANCELED*!!! Waves
can be canceled but the energy in the canceled waves must
change direction in a transmission line because there are
only two directions available. When fields cancel in one
direction, the energy in the fields must be re-distributed
in another direction. Given two, and only two, directions for
that re-distribution in a transmission line, what is it about
the following that you refuse to understand?
"... when two waves of equal amplitude and wavelength that are
180-degrees ... out of phase with each other meet, they are not
actually annihilated. All of the photon energy present in these
waves must somehow be recovered or redistributed in a new direction,
according to the law of energy conservation ... Instead, upon meeting,
the photons are redistributed to regions that permit constructive
interference, so the effect should be considered as a redistribution
of light waves and photon energy rather than the spontaneous
construction or destruction of light."
