Abstract

Pulsed terahertz time-domain systems rely on antennas printed on photoconductive substrates (PCA), which show extremely fast conductivity transients when illuminated by femto-seconds laser pulses. This work introduces a time domain representation of the PCA transmitter that accounts for time evolving voltages at the terminals of the photoconductive gap; such model is able to explain the saturation phenomena observed in measurements performed under high power laser excitations that previous models could not account for.
