Abstract

The interaction of spin waves propagating as directional modes in microwaves based on iron-yttrium garnet films has been examined. The configuration consists of three microwaves arranged in parallel, with air gaps separating them, allowing for the coupling between them. The source of this coupling is attributed to the long-range dynamic sagging (dipole) field of the precessing magnetization vector. A methodology is put forward to regulate the properties of this coupling by modulating the angle of the static magnetization with respect to the principal axes of the geometry. Micromagnetic modeling was employed to demonstrate the sub-magnetization angle-controlled propagation of spin waves along lateral microwaves. As a consequence of micromagnetic modeling, spin wave propagation spectra were obtained. The subsequent analysis of these spectra revealed that lateral microwaves can function as functional elements in planar magnonic networks, serving as directional taps, spin wave multiplexers, or microwave power dividers. Furthermore, the study demonstrated the capability to control spin wave routing between the microwaves («magnetic channels») through the modulation of the external magnetic field angle.
