Cecil,

I haven't the foggiest idea what model you might be using. I am using
the classical model that is found in virtually any textbook that deals
with plane waves in non-conducting media.

I don't have to "prove" anything. Just set up the standard wave
equations with the standard boundary conditions and the problem
practically solves itself. The non-zero remaining waves are all moving
in the same direction. I forgot to ask them if they realize that Cecil
doesn't approve of such behavior.

I suppose this is an prime example of being seduced by "math models",
but I believe that is a lesser fault than being seduced by Cecil's
imaginary models.

To prove that to be a true statement you must prove that the transistion
point between materials of different indices of refraction results in zero
reflections. Good luck on that one.

For instance, one can change the thin-film thickness from 1/4WL to 1/2WL
and cause exactly the opposite effect, i.e. extreme glare.

If you are using the quantum electrodynamics model, please let us know.
Most of the rest of us are using the EM wave reflection model.
