THE INVERSE PROBLEM OF RECOVERING ELECTROMAGNETIC AND GEOMETRIC PROPERTIES OF A MULTISECTIONAL ANISOTROPIC DIAPHRAGM IN A RECTANGULAR WAVEGUIDE

Abstract

Background. This paper is devoted to inverse problem of recovering electromagnetic and geometric properties of a multisectional anisotropic diaphragm in a rectangular waveguide. The aim of study is to develop numerical-analytical methods of solving inverse problems. Materials and methods. We consider inverse problem: inverse problem of permittivity and permeability tensors and thickness reconstruction of multisectional diaphragm. The problem is devoted to the boundary value problem for Maxwell’s equations. Results. We obtain numerical-analytical methods of the solution of the inverse problem. Conclusions. The numerical methods of solving the inverse problem and numerical results can be used in practice to reconstruct electromagnetic characteristics of modern materials.
