Abstract
Diffraction on periodic and quasi-periodic diffraction gratings (DR) formed by graphene ribbons is considered. The magnetic field is applied perpendicular to the graphene plane. Theoretical research is based on the solution of two types of integral equations. The first is paired addition equations in which the current density on graphene strips is unknown. The second is an integro-differential equation with respect to the electric field strength inside graphene strips. To calculate the characteristics of quasi-periodic DRs, the transition from the spectral representation of the fields of the periodic lattice to the spatial representation of the quasi-periodic was used using the Poisson transformation. The tuning of the frequency of plasmonic resonance (PR) by the magnetic field, the rotation of the plane of polarization of the reflected and transmitted waves, and the presence of additional PRs were investigated.
