Electromagnetic Scattering Analysis of a Conductor Coated by Multilayer Thin Materials

In this letter, an efficient numerical approach for the electromagnetic scattering analysis of the conductor coated by multilayer thin materials for closed bodies is proposed. Only the induced current on the conductor is needed to be discretized as the unknowns, so the number of unknowns is independent with the number of dielectric coating layers. For the model of a conductor coated by multilayer thin materials, the electric field integral equation (EFIE) is presented and the multilevel fast multipole method (MLFMM) is utilized to speed up the matrix vector product after these equations converted to matrix equations with Galerkin testing. To validate this approach, several numerical examples are presented.
