Improved Isolation Ratio in MSSWs‐Based Inline Interference Device Using Dipolar‐Coupled SWs Across a Micro‐Air Gap

Abstract Control of spin‐wave (SW) propagation is demonstrated by introducing a micro‐air gap into a nanometer‐thick yttrium iron garnet (Y3Fe5O12, YIG) microstructure. SWs traverse the gap with reduced intensity following an exponential–linear decay with air gap length, attributed to coupling betwe...
