Rabi-Like Splitting in Acoustic Cavity Coupled with Membrane-Type Metasurface

Abstract

Rabi-Like Splitting

In article number 2400340, Yuancheng Fan, Fuli Zhang, and co-workers present a hybrid metasurface made of a membrane-type acoustic metasurface and an acoustic cavity, which is promising for spectral modulation. The coupling of the local resonant mode of the membrane metasurface and the F-P mode of cavity shows a Rabi-splitting-like response. The splitting mechanism would be interesting in designing multi-band acoustic wave-functional devices.
