Graphene has been considered as a promising material which may find applications in the THz science. In this
work, we numerically investigate tunable photonic crystals in the THz range based on stacked graphene/dielelctric layers, a
complex pole–residue pair model is used to find the effective permittivity of graphene, which could be easily incorporated
into the finite-difference time domain (FDTD) algorithm. Two different schemes of photonic crystal used for extending the
bandgap have been simulated through this FDTD technique.
