Spatial-frequency signal selection based on spin-wave propagation effects in a YIG structure with intersecting waveguides and resonators

Abstract

Here we used micromagnetic modeling methods and the modern MuMax3 software package to study a complex YIG structure consisting of a system of orthogonal microwave guides with an integrated central ring resonator . Particular attention was paid to the analysis of nonlinear effects and the dynamic control of microwave propagation. Emphasis was placed on studying the characteristics of microwave propagation in the frequency range of 4.8-5.8 GHz. Magnetization maps and the effective field distribution were analyzed for the two main magnetic field directions. It was shown that the ring resonator leads to the emergence of new narrow bandwidths and channels for the redistribution of microwave energy between the different arms of the cross-shaped structure. The highest transmission efficiency
was observed at a frequency of 5.2 GHz, which is confirmed by the magnetization maps. It was found that changing the magnetic field direction leads to a significant change in the amplitude-frequency responses, demonstrating the possibility of dynamically controlling signal propagation channels and reconfiguring the device.
