Abstract

Using the MWS CST software package, the frequency dependences of the transmission and reflection coefficients of a normally incident TEM-wave (p- and s-polarized) through graphene nanoribbon (GNR) lattices have been calculated by using the Floquet channel method for various values of the external magnetic field applied perpendicular to the graphene plane in the terahertz range. The results of 3D scattering diagram simulations (radar cross section RCS, μm2) of a single-layer and multilayer (N = 3) GNR lattice cell at a magnetoplasmon resonance frequency of f0res = 10.614 THz under an applied magnetic field (B0 = 10 T) have been obtained. An increase in the RCS parameter of the transmitted and, especially, reflected wave from the multilayer GNR (compared to the single-layer GNR) has been demonstrated.
