ABSTRACT

This paper presents a hybrid technique for obtaining a numerical solution to the problem of scattering of the harmonic electromagnetic waves on a two-dimensional inhomogeneous scatterer. The scatterer is an infinite rectangular magneto-dielectric cylinder with an inhomogeneous cross section. Using the integral equation approach, the boundary conditions of the problem are reformulated in the form of integral equation of Fredholm of the second kind. The appropriate fast numerical algorithm corresponding to the problem is obtained by using the finite difference method. The results of numerical simulations obtained by implementing the proposed algorithm have been compared with the results obtained by using two electromagnetic software based on the different numerical methods. Some physical analysis of the above numerical results has been made in this study with a viewpoint of possible application.
