The Scattering of Electromagnetic Waves from Two-Dimensional Randomly Rough Perfectly Conducting Surfaces: The Full Angular Intensity Distribution

摘要

By a computer simulation approach we study the scattering of $p$- or$s$-polarized light from a two-dimensional, randomly rough, perfectlyconducting surface. The pair of coupled inhomogeneous integral equations fortwo independent tangential components of the magnetic field on the surface areconverted into matrix equations by the method of moments, which are then solvedby the biconjugate gradient stabilized method. The solutions are used tocalculate the mean differential reflection coefficient for given angles ofincidence and specified polarizations of the incident and scattered fields. Thefull angular distribution of the intensity of the scattered light is obtainedfor strongly randomly rough surfaces by a rigorous computer simulationapproach.
