Approximate methods for solving problems of the electromagnetic scattering from local inhomogeneities and partial radiation conditions

A theoretical study of electromagnetic processes is reduced to an investigation of solutions to the Maxwell equations for an inhomogeneous medium, which satisfy certain boundary conditions imposed on bodies of arbitrary shapes. Usually, an investigation of wave processes is a multiparameter problem, which can be successfully solved using simulation methods. An important class of mathematical models of wave stationary processes which occur in unbounded regions of the three-dimensional space includes models of the electromagnetic wave propagation in waveguides and stationary electromagnetic scattering from a body embedded in a locally inhomogeneous medium
