Making sound vortices by metasurfaces
Liping Ye, Chunyin Qiu, Jiuyang Lu +5
Based on the Huygens-Fresnel principle, a metasurface structure is designed to generate a sound vortex beam in airborne environment. The metasurface is constructed by a thin planar…
Highly efficient isolation of waterborne sound by an air-sealed metasurface
Xiaoxue Bai, Chunyin Qiu, Xinhua Wen +3
Underwater sound isolation has been a long-standing fundamental issue in industry and military fields. Starting from a simple theoretical model, here an air-sealed metasurface is p…
Extraordinary acoustic reflection enhancement by acoustically-transparent thin plates
Zhaojian He, Shasha Peng, Chunyin Qiu +6
We report an observation of the extraordinary high reflection of acoustic waves in water by thin epoxy plates partitioned by subwavelength cuts, whereas such plates without structu…
Acoustic transmission enhancement through a periodically-structured stiff plate without any opening
Zhaojian He, Han Jia, Chunyin Qiu +6
We report both experimentally and theoretically that the enhanced acoustic transmission can occur in the subwavelength region through a thin but stiff structured-plate without any…
