Development of Higher-Order DG-FETD Tool for Efficient Modeling of Complex Electromagnetic Structures

Discontinuous Galerkin finite-element time-domain (DG-FETD) method is one of the most attractive time domain techniques. It is a good combination of DG approach and FETD technique together with special features. Temasek Laboratories at National University of Singapore (TL@NUS) has put a lot of efforts to develop DG-FETD tool for efficient modeling of complex electromagnetic (EM) structures. This paper summarizes main techniques implemented in process of developing our DG-FETD tool that has been verified through the simulation of many EM structures.
