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…
Highly asymmetric interaction forces induced by acoustic waves in coupled plate structures
Xiying Fan, Chunyin Qiu, Shenwei Zhang +2
Mutual forces can be induced between coupled structures when illuminated by external acoustic waves. In this Letter, we propose a concept of asymmetric interaction between two coup…
Unidirectional propagation of designer surface acoustic waves
Jiuyang Lu, Chunyin Qiu, Manzhu Ke +1
We propose an efficient design route to generate unidirectional propagation of the designer surface acoustic waves. The whole system consists of a periodically corrugated rigid pla…
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…
Graded negative index lens with designable focal length by phononic crystal
Ke Deng, Yiqun Ding, Zhaojian He +3
We realize a flat lens with graded negative refractive index by a two-dimensional phononic crystal. The index-grade is achieved by gradual modification of the filling fraction alon…
