Abstract

The phase properties due to single-scattering from two- dimensional slightly random rough surfaces are presented. Much attention is paid to the intensity statistic in the specular direction, and it is shown that the specular intensity can be enhanced and reduced according to the phase properties. These effects are termed phase-related specular enhancement (PRSE) and phase-related specular reduction (PRSR). Several rough surfaces fabricated in the laboratory are used to demonstrate the theoretical analyses, and quite good coincidences are obtained.
