Graphene-Based Tunable Attenuator on Coplanar Waveguide

In this paper, a novel tunable attenuator based on graphene is proposed. The attenuator is composed of a graphene sandwich structure and a coplanar waveguide (CPW). By tuning the surface impedance of graphene, the insertion loss of transmission line can consequently be tuned. This attenuator present...

Summary:In this paper, a novel tunable attenuator based on graphene is proposed. The attenuator is composed of a graphene sandwich structure and a coplanar waveguide (CPW). By tuning the surface impedance of graphene, the insertion loss of transmission line can consequently be tuned. This attenuator present favorable attenuation ranges from 3dB to 15dB at a relatively wide frequency band from 10 GHz to 26 GHz.
