Time-Dependent Electromagnetic Wave Diffraction by Double Periodic Array

Abstract

A new difference scheme for the solution of a three-dimensional time-dependent problem of plane electromagnetic wave diffraction by a planar two-direction periodic structure of metal strip elements is constructed with the flow form of the Maxwell equations. The monotonicity principle is applied to upgrade the algorithm efficiency. Some calculated field characteristics in the problems of wave diffraction by periodic arrays of strip dipoles and C-shaped volumetric strip elements are demonstrated.
