Abstract

Using the MWS CST software, the diffraction of a TEM-wave (with the p-polarization) normally incident on the grating of graphene nanoribbons (GNRs) under applying a magnetic field in the direction perpendicular to the graphene plane is simulated. With the help of the MWS CST software, numerical analysis of the scattering pattern 3D e-Field in the far-field is performed for the vertical Еy and horizontal Ех components of the diffracted field for different values of magnetic induction B0 at the magnetoplasmon resonance frequencies. The results of calculation of the ratio Ех/Еу of the horizontal and vertical components of the diffracted field are obtained at the points of cross section (φ = 0) of the main lobe of the 3D e-Field scattering pattern; it is shown that the variation of the horizontal component Ех of the diffracted field as a function of magnetic induction B0, which is due to the gyrotropy of the graphene conductivity and the magnetooptical effects emerging in this case, is demonstrated.
