Abstract

The discontinuous Galerkin time-domain (DGTD) method is gaining popularity among computational electromagnetics (CEM) practitioners. This can be attributed to the fact that it has several advantages over the classical finite element method. The DGTD method realizes “information exchange” between neighboring spatial discretization elements using numerical flux. Therefore all spatial operations are localized within a given element leading to a block-diagonal mass matrix which is inverted very efficiently only once before the time marching starts. Consequently, if an explicit time integrator is used, the DGTD method becomes high compact and efficient.
