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.
