Abstract

The propagation of spin waves in a system composed of a Mach–Zehnder interferometer (MZI) and a transversally confined waveguide based on yttrium iron garnet has been investigated. Micromagnetic simulations demonstrate the possibility of using the system as a single-channel demultiplexer for spin-wave signals. It is shown that the distance between the MZI and the transversally confined waveguide, as well as variations in the waveguide width, affect both the phase shift of the propagating signal and the coupling efficiency in the interaction region. The demultiplexing characteristics of the structure are presented, revealing its potential for spatial–frequency signal selection. The proposed coupled waveguide–MZI system provides a basis for the implementation of logic operations and may be employed in integrated circuits based on magnonic principles.
