Scattering and radiation simulation by discontinuous Galerkin time domain method

In this paper, the implementation of the sources for scattering and radiation of the discontinuous Galerkin time domain method (DGTD) are presented. Based on formulations of the DGTD method, the sources implementation procedure is given, including the incident plane wave generated for scattering and the modeling of a coaxial port feed for antenna radiation. Numerical examples of PEC almond scattering and a microstrip antenna radiation are demonstrated the accuracy and efficiency for the source implementation in DGTD method.
