Query: Anti-mirror reflection of a bounded plane optical waveguide: string
  model   The effect of anti-mirror reflection from a bounded plane optical waveguide
used earlier for observation of slow light in a Bragg waveguide is considered.
A theory of the effect is proposed that allowed us to interpret the observed
spectral (Gaussian lineshape) and angular (Lorentzian angular profile)
properties of the light scattered by the bounded waveguide in the anti-specular
direction.
