Enhanced backscattering of light from deterministic quasi-periodic surfaces.
It is usually assumed that some randomness of a surface is required for the occurrence of the enhanced backscattering of light from it. We study numerically the scattering of s-polarized light from a quasi-periodic, perfectly conducting surface. We find that under certain conditions the angular distribution of the intensity of the light scattered by this deterministic surface displays a peak in the retroreflection direction-enhanced backscattering. This phenomenon is shown to be a multiple-scattering effect.
