Abstract:

To find solutions of electromagnetic scattering in nonuniform complex media is complex and difficult. This paper establishes difference equations of elec-tromagaetic scattering problem in complex media by integral interpolation me-thod to partial differential equation. The process of modeling and FDE's constru-citron applied in electromagnetic scattering problems in anisotropic and rotary wave zaedia are given. We also analyse in terception errors of difference equations. Numerical results of typical problems show that this method is valid.

Key words: electro-magnetic scattering, finite difference method, partial differential equation
