Paper Abstract

The dressed Rayleigh expansion is used to calculate the scattering of electromagnetic radiation from a randomly rough surface. This expansion was developed for grating calculation by Agassi and George [Phys. Rev. B 33, 2393-2400, 1986] to eliminate the numerical overflow, due to the evanescent waves, when the grating height is large. This dressed expansion involves redefining the expansion coefficient so that the matrix element is multiplied by an exponential damping factor. We find that this damping is too strong causing numerical underflow. As the root mean square (rms) roughness increases, the size of the expansion must decrease to avoid this numerical problem.
