Bb. Anderson et al., THRESHOLD EFFECTS IN LIGHT-SCATTERING FROM A BINARY DIFFRACTION GRATING, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 54(1), 1996, pp. 912-923
The theory of light scattering from an interface covered by a periodic
grating near the threshold of transformation of one of the diffractio
n beams from a traveling wave to an evanescent one is developed and co
mpared with experiments. It is shown that the behavior of the scattere
d light near such thresholds provides rich information regarding both
the medium in contact with the grating interface and the interface its
elf.
