Paper Abstract

In this work we consider a structure consisting of vacuum in the region x3$GTR(zetz) (x1); a dielectric film characterized by a real,positive, dielectric constant (epsilon) in the region -D < x3 < (zetz) (x1); and a vacuum in the region x3<-D. The surface profile function (zetz) (x1) is assumed to be a single-valued funtion of x1, that is differentiable, and constitutes a random process. This structure is illuminated from the region x3 $GTR (zetz) (x1) by s-polarized light whose plane of incidence is the x1x3-plane. By the use of the geometrical optics limit of phase perturbation theory we show how to design the surface profile function (zetz) (x1) in such a way that the mean differential transmission coefficient has a prescribed form within a specified range of the angle of transmission, and vanishes outside this range. In particular, we consider the case in which the transmitted intensity is constant within a specified range of the angle of transmission, and vanishes outsides it. Rigorous numerical simulation calculations show that the transmitted intensity indeed has this property.
