Abstract With their thin thicknesses and unprecedent wave manipulation capabilities, acoustic metasurfaces have a
great potential to be applied in a wide range of applications. Most existing metasurfaces are passive devices.
Although passive devices are easy to implement and consume no energy, one major shortcoming of passive
devices is their fixed and limited functionality, which greatly limits their application scope. To increase the
functionalities of a metasurface and yet still maintain its passivity, we propose to use the wave frequency as
a tuning freedom to realize multiple functionalities in one single passive device. Specifically, the passive More >
