Abstract
This paper summarizes algorithms, which extend the finite- difference time-domain calculation method to solve Maxwell's equations for terahertz (THz) electromagnetic radiation from photoconductive materials pumped by femtosecond laser pulses. In the calculations, we include transient electric conductivity by considering carrier dynamics. By using the newly proposed algorithms, we calculated the THz radiation from photoconductive antennas. The preliminary calculation results about the THz pulse generation, propagation, and radiation pattern are presented.
