Research progress of acoustic metasurface in China

Abstract

Acoustic metasurface (AMS) is an important branch of metamaterials which has important applications in various fields such as earthquake protection, noise reduction, acoustic hiding, architectural acoustics, particle manipulation, and medical ultrasound and therapy. The AMS with subwavelength thickness can manipulate the acoustic wave by controlling the wavefront phase based on the generalized acoustic Snell's law. In this review, the research and application progresses of AMS in China were introduced, and the further development trends of AMS were analyzed and remarked.
