An Efficient Solution for the Transient Electromagnetic Scattering From a Conductor Coated by Multilayer Thin Materials

An efficient multilayer thin dielectric sheet (TDS) formulation based on the marching-on-in-time (MOT) solver is proposed for the analysis of transient electromagnetic scattering from a conductor coated by multilayer thin materials. Like its frequency domain counterpart, all the sources in the thin dielectric coatings are represented in the terms of current densities on PEC surface. The proposed method can reduce the number of unknowns significantly while reasonable accuracy can be achieved. Several numerical examples are presented to demonstrate the accuracy and stability of the proposed method.
