Electromagnetic Waves in Graphene-Coated Partially Filled Chiroplasma Cylindrical Waveguide

This article presents a novel analytical model composed of monolayer graphene and core partially filled with chiroplasma. This presented analysis is generalized for any isotropic or anisotropic material having plasma and metamaterials. Cylindrical structure has been proposed for this analytical model to find the propagation and attenuation for hybrid waveguide HE11 and EH01 modes. To analyze the feasibility of our proposed structure, partially filled chiroplasma waveguide with monolayer graphene at cladding has been introduced. By using the suitable boundary conditions for the proposed structure, a novel matrix is obtained to examine and evaluate its dispersion relation and propagating parameters numerically. It is demonstrated that anisotropy of chiroplasma, chirality, and chemical potential of graphene can control and adjust the plasmonic features for proposed structure in the terahertz (THz) frequency regime. Harnessing the chiroplasma media with graphene layers can paving the way for fabrication and model the novel plasmonic devices in mid infrared region. The proposed structure and ana-lytical model can be exploited for many potential applications such as chiral sensing and chiroptical communication devices.
