Guided magnonic Michelson interferometer

Magnonics is an emerging field with potential applications in classical and quantum information processing. Freely propagating magnons in two-dimensional media suffer from dispersion, which limits their effective range and fidelity. We show the design of controllable magnonic circuitry, that utilise surface current carrying wires to create magnonic waveguides. We also show the design of a magnonic directional coupler and controllable Michelson interferometer to demonstrate its utility for information processing tasks.
