Abstract

This paper presents reconfigurable E-plane waveguide resonators at X-band. A graphene based switch and a silicon switch is used as the switching elements and is connected to the edge of a metallic fin. Through electrical biasing of the graphene or optical illumination of the silicon dice, a different length of the fin is realized, thus creating a shift in resonant frequency of the structure. Frequency shift of about 4.5% is achieved for the resonator using the graphene switch. As a reference, measured results of a fabricated optically reconfigurable resonator are compared to that of the simulated results of the graphene based reconfigurable resonator.
