Calculation of the Scattering Characteristics of Gaussian Wave Beams in Two-Dimensional Periodic Structures
Abstract
An algorithm is developed for calculating the electromagnetic characteristics of the scattering of three-dimensional Gaussian linearly polarized wave beam on the plane two-dimensional periodic structures. The incident beam spectral functions depending on its parameters have been obtained and studied. Frequency dependences of the reflection intensity of a plane wave and wave beam for normal incidence on a plane screen of finite thickness with rectangular openings are compared. For the cases of normal incidence of a circular beam, the field patterns of beams scattered on a plane two-dimensional periodic finitely thick screen with rectangular openings have been calculated. The electromagnetic field pattern narrowing effect of the transmitted beam has been found.
