Abstract

A recently developed numerical method is used to calculate the double-scattered Mueller matrices for scattering of vector-electromagnetic waves from rough surfaces. The method is based on a modified version of the Kirchhoff approximation and is valid for surfaces with vertical walls and for any surface material. Calculations are performed for the case of a single groove and a single rib on silicon and gold surfaces and results are compared to published experimental results. The calculated results of the 16 elements of the Mueller matrix as functions of the scatter angle show good qualitative agreement with the experimental results for the groove cases. Results for the rib cases show poorer agreement, possibly due to variations from the optimum parameters of the surface structure.
