The point is in absorption per propagation.

comment Total internal reflection for perpendicular incidence
Metals - I was thinking about them, but AFAIK they have high absorption, which also gives raise to high reflection (though, through a different mechanism). Or am I wrong?

@Simha I was thinking about it, but had some issues with logging in. :/ I will try again. :)

comment Total internal reflection for perpendicular incidence
@Ruslan Theoretic calculations based on interference of wave scattered from each atom layer. It results in both refraction and reflection from boundaries. For very strong coupling, and a certain phase of reflection, there is evanescence. Periodicity - you are right. By "uniform" I mean spatial period much, much smaller than (vacuum) wavelength.

@tom Because it misses evanescent depth (which, in my model, can be arbitrary). And for $n\to\infty$ you get 100% reflected, but no evanescent field at all.

@Sushant23 Did you read the last line? I am not a high-school student, I am a PhD.

comment Why does the BB84 paper “Quantum cryptography: Public key distribution and coin tossing” have a 'withdrawn' status?
@PeterShor I saw a few times an article being republished (I have no idea about its practical or legal side; especially I don't track which small journal/conference is owned by another). For an example, see this reprint of the original Shannon paper: dl.acm.org/citation.cfm?id=584093.
