Abstract
A computational algorithm for solving the boundary value problem of diffraction has been developed for Maxwell’s equations together with the Landau‒Lifshitz equation using the Galerkin projection method. Using the developed computational algorithm for calculating the conductivity matrix of an autonomous block with Floquet channels (FABs), the real and imaginary parts of the complex wavenumber of a quasi-extraordinary wave have been calculated from the solution of the characteristic equation depending on the bias field strength. Using the computational algorithm of the multilevel FAB recomposition, the mathematical modeling of diffraction of the fundamental wave on a 3D magnetic nanostructure in a rectangular waveguide has been carried out and the results obtained have been compared with the experiment.
