Interior Penalty DGTD Method for Electromagnetic Scattering Analysis of Dispersive Targets

摘要

In this paper, a paralleled interior penalty discontinuous Galerkin time domain method based on the second order vector wave equation (IPDG-WE) is proposed for electromagnetic scattering analysis of dispersive targets. Compared with the Maxwell's equation-based discontinuous Galerkin time domain (DGTD-ME) method, this proposed method enables efficient scattering analysis in terms of CPU time and memory consumption. Numerical results show the accuracy and efficiency of the IPDG-WE method.
