Modeling the interaction of an arbitrary light field with a diffraction grating by the Monte Carlo method

摘要

A high-accuracy solution of the diffraction problem has become necessary forthe treatment of certain special questions of statistical physics. This articlereports the creation of a computer program that serves as an instrumentalmethod of calculating the parameters of diffraction phenomena when complexoptical systems are being theoretically investigated. The program solves thediffraction problem by a rigorous method based on Maxwell"s equations underspecified boundary conditions. An arbitrary for instance, diffuse configurationof the initial light field is allowed. Reflective gratings with a linear orcrossed sinusoidal profile of the surface micro relief are considered as thediffraction optical elements. The characteristics of the self-consistent totallight field can be calculated when several diffraction elements are present inthe system.
