Finite Element Analysis of Scattering from 2D-Objects of Arbitrary Composition

Abstract

A number of techniques suggested for numerical analysis of scattering from 2D-objects with complex border shape and/or arbitrarily changing electromagnetic parameters (for brevity, from 2D-objects of arbitrary composition) is very large indeed, even if to take into account only the approaches based on finite element method (FEM). Nevertheless, some methodological and "technological" questions of FEM application have been under consideration ever since first implementations of the method. The task of correct field behavior description near the border, where the electromagnetic parameters change abruptly, belongs to the first group of questions. The convenient means of problem statement, such as specification of scattering object geometry and its electromagnetic parameters variation, is an important "technological" task.
