Two-dimensional random surfaces that act as circular diffusers
A. A. Maradudin, Tamara A. Leskova, Eugenio R. Méndez · Optics Letters · 2003
We propose a method for designing a two-dimensional random Dirichlet surface that, when it is illuminated at normal incidence by a scalar plane wave, scatters the wave with a circularly symmetric distribution of intensity. The method is applied to the design of 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.
