Abstract

The results of a numerical study of the polarization of a TEM-wave diffracted on a graphene nanoribbon grating in a perpendicular magnetic field at the plasmon and magnetoplasmon resonance frequencies are reported. Based on the analysis of the calculated ratio Ex/Ey of the horizontal and vertical components of the diffracted field and the axial ratio AR at the points of cross section (φ = 0°) of the main lobe of the 3D e-Field scattering patterns, the possibility of converting the linear polarization of the incident wave into the elliptical or circular polarization of the transmitted and reflected waves, depending on an external magnetic field value, is demonstrated.
