AbstractWave Computation Technologies, Inc. (WCT) proposes to develop a new time-domain discontinuous Galerkin software tool for modeling electromagnetic wave propagation through complex material and configurations. This solver combines the discontinuous Galerkin (DG) method with the finite-element time-domain (FETD) method to allow discontinuous discretization of complex geometry and materials. The solver will be implemented for arbitrary anistropoic and dispersive meda, so that novel materials including metamaterials can be included in the design simulation. The DG-FETD solver is highly efficient for complicated problems because it allows independent meshing and resolution for different regions. The WCT team has extensive experience with the relevant computational electromagnetics algorithms, and is in an excellent position to develop such a computational electromagnetics software tool. The proposed time-domain solver will further extend the application domain of the conventional finite element method to include large array of frequency selective surfaces and other complex electromagnetic environments.
