PROJECT TITLE :

Use of Terahertz Photoconductive Sources to Characterize Tunable Graphene RF Plasmonic Antennas

ABSTRACT:

Graphene, attributable to its ability to support plasmon polariton waves within the terahertz frequency range, permits the miniaturization and electrical tunability of antennas to permit wireless communications among nanosystems. One amongst the main challenges in the characterization and demonstration of graphene antennas is finding suitable terahertz sources to feed the antenna. This paper characterizes the performance of a graphene RF plasmonic antenna fed with a photoconductive supply. The terahertz source is modeled and, by suggests that of a full-wave EM solver, the radiated power as well because the tunable resonant frequency of the device is estimated with respect to material, laser illumination, and antenna geometry parameters. The results show that with this setup the antenna radiates terahertz pulses with a mean power up to one µW and shows promising electrical frequency tunability.
