Resumo

Two methods have been used to solve the boundary value problem of diffraction of a plane electromagnetic wave on a diffraction grating of graphene strips in the presence of a magnetic field. In solving the obtained integral and paired adder equations, the Galerkin method was used with a basis in the form of Legendre and Hegenbauer polynomials. As a result, systems of linear algebraic equations with fast internal convergence were obtained. All matrix elements of the system are expressed explicitly.
