Controlled spin-wave transport in a magnon-crystal structure with a one-dimensional array of holes

Spin-wave transport in a lateral system of microwaveguides coupled to each other through a magnonic crystal structure with a one-dimensional array of holes has been analyzed. Mechanisms of controlling a spin-wave signal at the tangential magnetization of the structure have been studied by the micromagnetic simulation and Brillouin spectroscopy. It has been shown that the anisotropy of the shape in region of coupling of spin waves propagating through isolated channels can be effectively changed under the variation of the magnetization angle of the structure, which allows controlling spatial and frequency selective regimes of spin-wave transport. The proposed structure can be used as a functional element of interconnections in planar topologies of magnonic networks and devices for parallel processing of a signal based on them.
