Numerical simulation methods for rough surface scattering

Numerical methods are of great importance in the study of electromagnetic s cattering from random rough surfaces. This review provides an overview of r ough surface scattering and application areas of current interest, and surv eys research in numerical simulation methods for both one- and two-dimensio nal surfaces. Approaches considered include numerical methods based on anal ytical scattering approximations, differential equation methods and surface integral equation methods. Emphasis is placed on recent advances such as r apidly converging iterative solvers for rough surface problems and fast met hods for increasing the computational efficiency of integral equation solve rs.
