MAGNETICALLY BIASED GRAPHENE-BASED SWITCHES FOR MICROWAVE APPLICATIONS

摘要

This article presents a magnetically biased graphene-based switch for coplanar waveguides (CPW) resonator applications. Graphene patches are set in the gap between signal and ground lines, thus, obtaining the whole structures act as switchable elements. Graphene was modeled as a general material with appropriate surface conductivity. The presented CPW resonator structure acts like a switch in ON state even for magnetic bias field of around 0.5 T. The simulated S parameters of the CPW resonator structure with different magnetic field biasing are presented. (C) 2015 Wiley Periodicals, Inc.
