Effective modeling of graphene as a conducting sheet in the Finite-Difference Time-Domain method

An effective approach for Finite-Difference Time-Domain modeling of graphene as a conducting sheet is presented. A novel technique for implementing a conducting sheet boundary condition in the FDTD method which is based on use of backward- and forward-difference schemes for the spatial derivatives is used for modeling of graphene sheet. Numerical examples are presented to show accuracy and applicability of the method.
