ELECTROMAGNETIC SCATTERING ANALYSIS OF A CONDUCTOR COATED BY THIN BI-ISOTROPY MEDIA

摘要

In this article, an efficient numerical approach for the electromagnetic scattering analysis of a conductor coated by thin biisotropy medias is proposed. Only the induced current on the conductor is needed to be discretized as the unknowns, the volume electric/magnetic current densities in dielectric layer are all represented in terms of current densities on the metal surface. For the model of the conductor coated by bi-isotropy media, the electric field integral equation is presented, and the multilevel fast multipole method is utilized to speed up the matrix vector product after these equations converted to matrix equations with Galerkin's test.
