Parallel DGTD Method for Transient Electromagnetic Problems

In this paper, a parallel discontinuous Galerkin time-domain (DGTD) method is developed for transient electromagnetic (EM) problems. In this method, the excitation is introduced by sorts of plane wave through total field/scattered field (TF/SF) boundary condition, and perfect matching layer (PML) is used to enhance reflected wave absorption. Also the DGTD is parallelized on a parallel unstructured mesh framework called JAUMIN. The method is applied to simulate a real computer case illuminated by EM pulse. The numerical results show the efficiency and accuracy of the proposed algorithm. And the data obtained by the numerical simulation could give great support to the design of protection measures of computer case in the EM pulse environment.
