Caracterización de antenas fotoconductoras en los THz

This paper describes an experimental model for determining the characterization of a photoconductive antenna in the terahertz band, in order to detect images in this frequency band. The photoconductive antennas consist of a pair of metal electrodes deposited on a semiconductor substrate, e.g., GaAs...
