An effective compact-FDTD wideband modeling of graphene conductivity

This paper demonstrates a competent rational polynomial method for efficient computational modelling of graphene surface conductivity using compact framework in the finite-difference time domain (FDTD) method that shape out graphene conductivity. The update equations of graphene surface conductivity using the proposed model in compact-FDTD (C-FDTD) method are developed. Numerical identity is presented to show the accuracy of the proposed approach and validation is obtained by comparing with exact formulism.
