Spin-wave signal rejection in magnonic waveguides induced by conducting films with a single groove
Year: 2024
Type: article
Abstract: Magnonic crystals, artificial magnetic media with periodically modulated properties, are a powerful tool for processing microwave signals, but generally require several millimeters of periodic structure. The authors present an innovative approach to circumvent this issue through a magnonic waveguide covered by a VO${}_{2}$ stripe with a shaped microgroove. Simulations show that such a structure does not manifest noticeable spin-wave reflection, but still demonstrates a rejection band in its transmission characteristic. The obtained findings pave a clear way forward to microminiaturizing spin-wave devices, where features of magnonic crystals are exploited.
