The only thing which can cause energy to change direction is reflection.
I have answered that question every time you asked it. Perhaps you
were just unable to grasp the meaning of the answer. It means that for
an electromagnetic wave to reverse direction, it must encounter a change
in the nature of the conducting medium.

Interference results when two or more waves superpose. The pattern is
the amplitude resultant plotted as a function of position. It may be
generated as a result of a reflection, but is not an entity which itself
reflects waves. Impedance discontinuities or changes in the index of
refraction - those things cause reflection. An interference pattern
created by waves is still just waves arranged differently. Waves don't
cause other waves to change direction. If you think they do, then you
need to try to find some proof. Adding your misguided editorials to
desriptions of interference doesn't qualify.
