Abstract

A high-accuracy solution of the diffraction problem has become necessary for the treatment of certain special questions of statistical physics. This article reports the creation of a computer program that serves as an instrumental method of calculating the parameters of diffraction phenomena when complex optical systems are being theoretically investigated. The program solves the diffraction problem by a rigorous method based on Maxwell"s equations under specified boundary conditions. An arbitrary for instance, diffuse configuration of the initial light field is allowed. Reflective gratings with a linear or crossed sinusoidal profile of the surface micro relief are considered as the diffraction optical elements. The characteristics of the self-consistent total light field can be calculated when several diffraction elements are present in the system.
