Abstract:
Recently a modification of the Kirchhoff approximation was presented to permit the calculation of multiple-scattered light on rough surfaces with infinite slopes. A brief description of the method, with examples of the scattering of light from rough surfaces with rectangular grooves, is presented. It is shown that, for a surface with random groove depths with a constant probability distribution of the groove depths, the backscatter intensity can increase or decrease, depending on the width of this probability distribution.
