In general, it will not. This is what calls into question
whether the reflected wave actually contains energy.

Virtually every EM wave you see with your own eyes is
a reflection. For you to argue that there is no energy
in those reflected EM waves is ridiculous in the extreme.
Exactly how do your optic nerves detect photons that
contain no energy? Hey, maybe that's why you are
hallucinating. :-)

This again calls into question the concept of power
in a reflected wave, since there is no accounting
for where that "power" goes.

That you fail to understand where the EM reflected wave
energy goes is simply ignorance. Please alleviate your
ignorance on the subject and the problem will go away.
Optical physicists have been tracking that energy for
centuries. Where have you been for the past three
centuries? :-)

I suggest you start with Eugene Hecht's chapter on
interference in "Optics". You will learn about
destructive interference, constructive interference,
and why those two must balance. All of the ExH energy
in an EM wave is conserved. You are simply ignorant
of how that energy is conserved.
