Dispersion Characteristics and Sensitivity Properties of Graphene Surface Plasmon Sensor

Abstract

In this work, dispersion characteristics and sensitivity of the propagation of TM surface plasmon through the proposed waveguide sensor. The proposed sensor containing a graphene at a finite distance filled with metamaterials (MTM) from plasmonic layer and sandwiched by dielectric layers. We numerically demonstrate the proposed waveguide structure as a novel graphene surface plasmons sensor. The obtained results can be useful for enhancing the sensitivity of plasmonic—graphene devices which could be used in further application in biosensing and environmental control.
