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.
