Description:
Author(s): Sheng-Dong Zhao, A-Li Chen, Yue-Sheng Wang, and Chuanzeng Zhang Fixed properties are one thing, but the design of t u n a b l e metasurfaces is significant for real-world applications, as an integrated, active control mechanism is much more resilient to the actual requirements of an ever-changing environment. However, design is often limited by the difficulty of finding a suitable tuning mechanism. The authors here design a tunable acoustic metasurface consisting of helical cylinders screwed into a circular plate. This screw-and-nut setup is used to obtain arbitrary phase profiles over a wide frequency range, and furthermore may inspire other sorts of designs. [Phys. Rev.
