Graphene Based Absorber Using LTJEC FDTD
2018 IEEE International Conference on Computational Electromagnetics (ICCEM)(2018)
Abstract
A terahertz absorber using graphene is simulated using Laplace transform current density convolution finite difference time-domain method. The absorber with approximately unity absorption is designed with a graphene ribbon array and a graphene sheet. The numerical results are presented to validate the proposed structure and demonstrate that the graphene sheet is an appropriate material to develop a broadband absorber.
