Monte Carlo Calculation for Electromagnetic-Wave Scattering from Random Rough Surfaces

Abstract

A Monte Carlo calculation for light intensities scattered from a random Gaussian-correlated surface is presented for the first time. It is shown that small randomness on a grating surface can considerably change the intensities and, in particular, the surface polariton resonances. These results should be used to check perturbation-theory calculations. © 1984 The American Physical Society.
