A discontinuous Galerkin finite-element time-domain (DGFETD) port formulation of the coupled Maxwell's equations and Drift-Diffusion equations for a photoconductive antenna is derived. The formulation is cast in a form such that static quantities are extracted. The resulting system is used to analyze terahertz-band photoconductive antennas with well-defined gap regions excited by pulsed lasers. Several antenna types are investigated, and results are compared to measured results from the literature.
