| Popis: | This article presents an improved anisotropic wave concept iterative process (WCIP) algorithm for the analysis of a novel type of tunable graphene-based coupler at the terahertz band for different physical graphene parameters. Through the novel technique of implementation of the anisotropic boundary conditions in the WCIP method, we can integrate the anisotropic surface conductivity matrix into this algorithm without implying a volumetric discretization. Numerical examples are presented to verify the efficiency of the proposed algorithm. The numerical simulation results demonstrate that the performance of the coupler can be controlled by varying the chemical potential and the magnetic field, and a little change was obtained with the variation of the relaxation time and the temperature of graphene. |
