Abstract
We propose a method for designing a two-dimensional random Dirichlet surface which, when illuminated normally by a scalar plane wave, scatters it with a prescribed circularly symmetric distribution of intensity. The method is applied to the design of a surface that scatters light uniformly within a circular region and produces no scattering outside that region, and a surface that acts as a Lambertian diffuser. The method is tested by computer simulations, and a procedure for fabricating such surfaces on photoresist is described.
