Reconfigurable and Phase-Engineered Acoustic Metasurfaces for Broadband Wavefront Manipulation (Adv. Phys. Res. 4/2024)

Abstract

Acoustic Metasurfaces

In article number 2300128, Zhonggang Wang and co-workers report a novel type of phase-engineered acoustic metasurface composed of meta-elements with robust phase difference. The cover image shows an acoustic metasurface featuring reconfigurable properties, enabling the flexible broadband manipulation of reflected wavefronts. This achievement has favorable implications for generally applicable structures applied in multiple scenarios including biomedical acoustics, noise control and so on.
