Abstract
A method for broadband, high-efficiency spin wave transduction adopts a slow-wave structure to enhance the interaction of electromagnetic waves and spin waves.
Claims9
A device comprising:
- a spoof surface plasmon polariton (SSPP) waveguide;
- and
- a magnetic resonator comprising a ferromagnetic insulator disposed on the SSPP waveguide, the magnetic resonator coupling with a spoof surface plasmon polariton mode of the SSPP waveguide through magnetic dipole-dipole interaction.
