Modified graphene conductivity modeling for the application of optical based plasmonic devices

Abstract

In this paper we have proposed modified optical conductivity model of graphene and simulated surface-plasmon polariton (SPP) mode propagation for different chemical potentials. We have approximated the critical value of chemical potentials which is responsible for (SPP) propagation in Single layer straight and double layer 90 Degree sharp bending using Finite Difference Time Domain method (FDTD) with SBC-Perfectly Matched Layer (PML) technique. The possible application of SPP for the plasmonic devices is discussed.
