This study explores the application of spin waves for developing functional components for information processing, transmission, and storage within the microwave and terahertz frequency regimes. The platform is based on yttrium iron garnet (YIG) thin films, with spin wave manipulation achieved via two-dimensional arrays of magnetite cylinders. A numerical micromagnetic analysis of a cross-shaped waveguide was conducted by solving the Landau-Lifshitz-Gilbert equation, examining the dependence of wave properties on the orientation of the external magnetic field. The findings indicate a viable pathway toward the realization of compact and energy-efficient magnonic devices.
