摘要

This paper explores recent theoretical advancements and experimental observations of bound states in the continuum (BICs) in acoustic, elastic, and optomechanical systems. We focus on three main types of BICs: symmetry-protected, Friedrich-Wintgen, and Fabry-Pérot BICs, and discuss their extensions to complex systems. Our work aims to bridge the theoretical and experimental validations of BICs, highlighting their utility and future development in mechanical wave systems.
