Reflection and transmission characteristics of a slab with periodically varying surfaces
Abstract
Using a plane wave spectral decomposition of the relevant electromagnetic (EM) fields and the Tmatrix solution philosophy, a Tmatrix is formulated which completely characterizes the EM response of an infinite material plate bounded by two homogeneous halfspaces, the two interfaces being periodically rough. Individual Tmatrices for either of the two periodic bimaterial interfaces are used in this derivation. Using the computed results, the anomalies in the scattering response of the rough slab are explained in terms of reflectionless and transmissionless modes, the Brewster angle, and the conditions for propagation or evanescence of a given plane wave mode.
