Directional Microwave Coupler Based on Neuromorphic Network of Lateral Magnetic Micro- and Nanowaveguides

The surface and backward volume magnetostatic spin waves propagation in the side-coupled magnonic micro- nanowaveguides was numerically studied. The dispersion characteristics was calculated using the modification of finite element method. The transformation of the frequency dependence of the coupling length with the variation of the geometrical parameters was investigated. The cases of surface and backward volume magnetostatic waves were considered. It was shown that the coupling length is increased in the surface wave geometry. The influence of the external bias magnetic field orientation on the spectra of wave in lateral structures was demonstrated. The neuromorphic network of lateral stripes can be used in the pattern recognition methods.
