Reflected wavefront manipulation based on ultrathin planar acoustic metasurfaces. [PDF]
Sci Rep, 2013 The introduction of metasurfaces has renewed the Snell's law and opened up new degrees of freedom to tailor the optical wavefront at will. Here, we theoretically demonstrate that the generalized Snell's law can be achieved for reflected acoustic waves based on ultrathin planar acoustic metasurfaces.
