Abstract: Features of spin-wave dynamics in a ring magnonic microwaveguide that appear at change in the direction of the equilibrium magnetization with respect to the axis of symmetry of the structure have been studied by micromagnetic simulation based on the numerical solution of the Landau–Lifshitz–Gilbert equation. Mechanisms of control of lateral spin wave transport in yttrium iron garnet stripes located along the parallel sides of the ring magnonic microwaveguide have been considered. The possibility of the inversion of the group velocity of a spin wave with the simultaneous selection of transverse spin-waveguide modes in the lateral structure has been demonstrated. It has been shown that the method proposed to control the direction of transfer of the spin wave power can be used to fabricate controllable integrated units of functional magnonic circuits with the simultaneous spatial-frequency selection of an information signal.
