Up to now, we have proposed different designs of acoustic metasurface (one-dimensional varying and two-dimensional varying metasurfaces, and active metasurface) and acoustic metastructure, in order to manipulate sound properties as much as we want (sound wavefront, vibrational orientation, acoustic focusing, and density-near-zero property). We also have demonstrated many novel acoustic applications on the basis of our designs, such as acoustic illusion and ipsilateral focusing, conversion from propagating to surface waves, generation of an acoustic focal needle and acoustic far-field multiple foci, super-oscillatory super resolution, and acoustic invisibility cloaking.
