Full-Wave Analysis of the Shielding Effectiveness of Thin Graphene Sheets with the 3D Unidirectionally Collocated HIE-FDTD Method

Figure 4

Discretization along the -axis. The vacuum part of the grid is uniformly discretized with step . The graphene sheet is approximated by two small UCHIE cells of size . The graphene conductivity is solely assigned to the single discretization point enclosed by these two small cells and does not need to be averaged as is the case for the conventional Yee grid.
