Abstract :
A simple but efficient finite-difference time-domain (FDTD) method integrated with auxiliary differential equation (ADE) for modelling periodic graphene-based structures is proposed. Based on the integral form of Ampere´s circuital law, the derived equations are simpler than those of subcell method proposed by the others. Numerical experiments are carried out to validate our method in comparison with the results of analytical and commercial software CST. It is further applied to study some periodic graphene-based Split-Ring Resonators (GSRR) structures, and their tunable transmission properties are investigated.
