Application of the principle of decomposition for the construction of mathematical models of spin-wave devices

  • E. V. Kudinov
  • A. S. Beregov


The fundamentals of the decomposition approach in the mathematical modeling of spin-wave devices are presented. In this approach the device is partitioned into autonomous blocks connected by wave channels. The use of multiwave scattering and transmission matrices as descriptors of the autonomous blocks is examined. The problem of the transmission of a signal carried by the spin waves in a dispersive waveguiding structure is solved as an illustration of the analytical approach to the construction of the descriptor of the autonomous block. The magnetic permeability tensor is obtained for an arbitrarily magnetized disoriented film (111) taking into account the cubic and induced anisotropy; the dispersion relation for spin waves in a regular waveguiding structure with an anisotropic film, completely determining the descriptor of an autonomous block, corresponding to a segment of such a waveguiding structure, is derived.
