Electromagnetic Model of a Nanodipole Array above a Double-Layer Graphene in Terahertz

In this paper we present an electromagnetic model of a Nanodipole Array above a Double-Layer Graphene (DLG) by Green’s Functions. In this approach, graphene layers are defined as surface impedances at the interfaces between the media. The electromagnetic fields are defined by the spectral representation of the Periodic Green’s Function using the complex Fourier series transform. The main objective of this work is to propose an equivalent electromagnetic model for a Surface Plasmon Resonance sensor (SPR sensor) that operates at the Terahertz frequency. As results, we present the electromagnetic fields radiated in the structure. As a form of validation, we compared the proposed model with a model developed in a software based on the Finite Element Method (FEM).
