A Novel Analytical Study of Anisotropic Multi-Layer Elliptical Structures Containing Graphene Layers

摘要: This article aims to propose a novel analytical model for anisotropic multi-layer elliptical structures incorporating graphene layers. The structure is formed of various magnetic materials, and each one has the permittivity permeability tensors $\overline {\overline {\varepsilon }}$ {\mu , respectively. An external bias been applied in axial direction. A layer, with isotropic surface conductivity ${\sigma }$ sandwiched between two adjacent materials. matrix representation derived find propagation parameters structure. Two exemplary important cases proposed general structure, as waveguides, have investigated show, first, validity our second, richness simulation results show an excellent agreement. very large value figure merit (FOM), e.g., FOM = 110, achieved second chemical potential ${\mu }_{\text{c}}={0.9}$ eV ${B}_{0}=1$ T, Our its can be exploited design innovative terahertz devices such absorbers, couplers, cloaks.
