Abstract

This paper presents the design, analysis, and developments of a reconfigurable hybrid metal-graphene filter for terahertz applications. In fact, through the graphene material, we can reconfigure both the resonance frequency and the bandwidth. Further, the variation in chemical potential, relaxation times, and temperature of graphene provides excellent proprieties performances, with a variation of the resonant frequency from 8.60 THz to 8.85 THz, good return loss reaching -22.94 dB and a bandwidth reconfiguration from 1.717 THz to 1.930 THz. The simulation of the proposed filter is performed using CST software.
