Owing to the novel properties based on the regulatory mechanism and physical design,acoustic metasurfaces have important potential applications in various fields.As an important branch of acoustic metamaterials,the metasurfaces can regulate the acoustic wave by controlling the wavefront phase,which obeys the generalized Snell’s law.In this paper,the research and application advances of acoustic metasurfaces were introduced,and the problems and trends in the future were discussed.This will be of certain guiding significance for the preparation and design of wave control structure made of metasrufaces.
