Neuromorphic Calculations Using Lateral Arrays of Magnetic Microstructures with Broken Translational Symmetry

详细

A possibility to control the characteristics of spin waves in a lateral array of magnetic microstructures with broken translational symmetry is demonstrated. The regimes of spatial and frequency selection of the spinwave signal are studied by Brillouin light scattering and by numerical simulations. The micromagnetic simulation is used to study the effect of geometric parameters on the characteristics of dipole-coupled spin waves. The specific features of the coupling between the transverse modes propagating in the system with broken translational symmetry are revealed. The results can be applied to develop multiplexers, power dividers, couplers, and the ultrahigh frequency signal processing circuits using the neuromorphic principles, which are based on the lateral arrays of magnetic microstructures.
