Characterization of graphene-based photonic crystal in THz spectrum with finite-difference time domain method Hai, Lin Di, Xu Fernández Pantoja, Mario Alberto González García, Salvador He-Lin, Yang Graphene Photonic cyrstal 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. 2018-04-11T08:14:59Z 2018-04-11T08:14:59Z 2014 info:eu-repo/semantics/article Hai, Lin; et. al.
