Default Constructive interference in radiowave propagation

Right. But the question still remains, what is your claim regarding the
exact nature of the "redistribution" if NOT reflection from a partially
reflective surface?


It is impossible for a "partially reflective surface"
to reflect 100% of the intensity. My two step process
explains 100% reflection. Walt's virtual short explains
100% reflection. How do *you* explain 100% reflection
from a partially reflective surface? Time to cease the
mealy-mouthing and hand-waving and give us some facts.

A B
i=1.0 | i=5.83 | i=1.0
100w laser---air---|--1/2WL thin-film--|---air---...
--Pref1=0w | --Pref2=100w | --Pref3=0w
Pfor1=100w | Pfor2=200w-- | Pfor3=100w--

The intensity reflection coefficient seen by the internal
reflected wave is 0.5 yet the net reflection is 100%. I
have explained how that is possible through wave cancellation.
You have not explained how that is possible without wave
cancellation. Time to put up or shut up.
