Investigation of the propagation of spin waves in the corrugated waveguide-planar waveguide system when changing the modulation parameters

The influence of the period filling parameter in the lateral system planar waveguide/corrugated waveguide is investigated by the method of micromagnetic modeling. The modes of switching the propagation of spin waves to the output ports are shown. When a defective region is added to the system – a region without periodicity – the transmission spectrum changes, and additional frequency regions of wave transmission appear. Based on the results obtained, it is possible to create a directional coupler applicable to information signal processing devices based on the principles of magnonics.
