Electrodynamic analysis of transmission coefficient of H 10 mode through slabs of nanocomposites, containing arrays of carbon nanotubes with magnetic nanoparticles, in waveguide at condition of ferromagnetic resonance

The mathematical model of diffraction of wave modes on the samples of nanocomposites, based on arrays of carbon nanotubes with magnetic nanoparticles, was developed taking into account the exchange interaction and boundary conditions. The computational algorithm for calculation of scattering parameters of S-matrix for 3D magnetic nanostructures in waveguides was created by using the multilevel re-composition of autonomous blocks with Floquet channels. Using the numerical autonomous blocks with Floquet channels method the results of electrodynamic calculation of the transmission coefficients of H 10 mode through slabs of nanomaterials based on the periodic 3D-arrays of oriented carbon nanotubes with magnetic Co 80Ni 20 nanoparticles, in the rectangular waveguide, depending on the direction and the value of DC bias magnetic field at different orientation with respect to CNT axis and rf magnetic field for several values of the filling factor of encapsulated magnetic nanoparticles were obtained at condition of ferromagnetic resonance at frequency of f = 26 GHz.
