Abstract

Photoconductive dipole antennas are promising candidates for efficiently converting laser light into a broadband terahertz wave. We present a finite integration technique analysis of these antennas in free space by using an analytic transient current excitation in the photoconductive substrate and including the effects of the receiving antenna. We show that the far-field spectral characteristics coincide well with the measurement results, and as our model does not rely on a wide laser pulse or require a trial-and-error fabrication design method, the electromagnetic simulations mean that the direct design of photoconductive antennas with desired spectral characteristics is practical.
