A time domain discontinuous Galerkin method for analysis of scattering from PEC objects

A time-domain discontinuous Galerkin method is presented to analyze transient scattering from perfect electrically conducting (PEC) objects. As mono-polar RWG functions are chosen for spatial functions, it is possible to analyze complex structures with either conformai or non-conformal discretization. Numerical results are included to demonstrate the accuracy and efficiency of this method.
