Parallel Broadband Finite Element Time Domain Algorithm Implemented to Dispersive Electromagnetic Problem
The numerical analysis of some broadband electromagnetic fields and frequency-dependent materials using a time domain method is the main subject of this paper. The spatial and time-dependent distribution of the electromagnetic field is approximated by the finite element method. The parallel form of the algorithm valid for some linear materials, and the formulation of the FE code for a dispersive electromagnetic problem are presented and compared. The complex forms of these algorithms have an effect on the memory and computational costs of the distributed formulation. The properties of the algorithm are estimated using high performance cluster of workstations.
