Switchable Bidirectional Sound Absorption Via Exceptional Point Modulation in Acoustic Metastructures with Interleaved Resonator Coupling (Adv. Sci. 44/2025)

Physics-Driven Acoustic Metastructure In their Research Article (DOI: 10.1002/advs.202508951), Zhonggang Wang, Zhendong Li, Zheng Fan, and co-workers present a physics-driven acoustic metastructure that employs exceptional point modulation and interleaved resonator coupling to achieve switchable bidirectional sound absorption. The cover image illustrates its compact deep-subwavelength design, offering promising opportunities for tunable applications in advanced materials and noise-control engineering.
