چکیده مقاله

A new design based on a metamaterial superstrate structure for THz photoconductive antennas is  reported herein. To enhance the THz output frequency peaks, the use of metamaterials on THz photoconductive antennas is proposed, and simulated by using the CST Microwave Studio software. Use of such a metamaterial superstrate structure over the electrodes of an antenna
leads to an enhancement of the frequency peak from 0.8 to 1.3 THz.
