Spin wave propagation in an array YIG microwaveguides at variations of the magnetization angle

Abstract

In the present work, a study of the dual control of the SW characteristics in arrays of YIG microwave waveguides at realization of simultaneously lateral and vertical types of coupling is carried out. A study of the peculiarities of the processes of spin-wave beam formation for a system of coupled layers with an array of magnetic waveguides has been carried out. The mechanisms of change in the spatial distribution of the spin-wave beam profile at the joint manifestation of the effects of anisotropic signal propagation and dipole coupling have been revealed. On the basis of the obtained spatial distributions of the components of the dynamic magnetization of the SW, a change in the character of the localization of the SW power in the output sections of the microwaves is demonstrated. It is shown that the deviation of the submagnetization angle from the direction in which the surface magnetostatic wave is excited in the central channels leads to the transformation of the transverse structure of the spin-wave beam, allowing to change the position of the spatial localization of the SW power.
