Abstract
Using a developed computational algorithm based on multilevel recomposition of autonomous blocks with Floquet channels, mathematical modeling of diffraction of the fundamental mode has been carried out on a magnetic nanostructure based on a 3D array of magnetically functionalized carbon nanotubes (MFCNTs) in a waveguide depending on the bias field under the ferromagnetic resonance conditions in the millimeter wavelength range. Using the developed special computational algorithm for determining bifurcation points of the nonlinear Maxwell operator (Maxwell’s equations together with the Landau‒Lifshitz equation), the thresholds of parametric excitation of the non-exchange magnetostatic waves and dipole-exchange spin waves in a periodic 2D array of MFCNTs have been calculated depending on values of the bifurcation parameters (pump wave amplitude and frequency).
期刊介绍：
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
