Abstract

This paper presents a time-domain numerical method to analyze photoconductive antennas operating in the terahertz regime. Theoretical basis of the formulation relies on the combination of the solutions of Poisson´s equation, carrier-transport equations, and Maxwell´s equations. Numerical results, achieved by employing finite-difference schemes, agree with experimentally measured electromagnetic fields.
