Principle of reversibility and some physical characteristics of wave scattering on diffraction gratings
Abstract
The general characteristics of fields scattered by various obstacles are studied, and corresponding boundary value problems are set up. These characteristics are obtained with the aid of Lorentz' lemma, and they serve as a criterion for the numerical solution of the boundary value problems and allow drawing a priori conclusions concerning the properties of actual gratings. The principle of reversibility is used to study the relationship between field values at various points in space, and attention is focused on reversibility relationships that make it possible to relate the matrix coefficients of wave scattering on periodic structures.
