Split-post re-entrant microwave displacement transducer with quadratic readout

Abstract We investigate a microwave-cavity-based displacement readout employing a split-post geometry to measure the motion of a dielectric membrane. Due to symmetry, the cavity response to membrane displacement is inherently quadratic when the membrane is positioned at the centr...

Multi-mode input–output model for cavity magnonics: Phase-resolved control of level repulsion, level attraction, and nonreciprocal transmission

We experimentally validate a unified input–output model that incorporates internal and external coupling phases across multiple cavity modes in a room-temperature cavity magnonic system. By explicitly accounting for both phase contributions, the model provides a clear interpretat...
