Numerical Analysis of a Graphene Surface Plasmon Resonance Sensor in Terahertz

In this paper, we present a numerical analysis of a plasmonic sensor based on Single-Layer Graphene operating as a refractometer in the terahertz range. The Kretschmann configuration, where the operating angle is the variable that monitors reflectivity, is used. Using the Finite Element Method (FEM), the proposed device was simulated in a software. Parametric analyzes were performed to verify the ...
