RE: ATM Anti reflection coatings and TDE (not related)

Almost sounds like a break down in causality or the old time travel paradox,
doesn't it.  I think the reason it works is that the film is smaller than
the wavelength of the photon.  So rather than reflecting, cancelling, and
thereby not reflecting in the first place, we have a situation where a
photon comes to what it sees as a very thin film and finds it cannot
reflect.  (Maybe there just isn't room to turn around in that small space?)
