Brillouin Klein space and half-turn space in three-dimensional acoustic crystals
Zhenxiao Zhu, Linyun Yang, Jien Wu +14
The Bloch band theory and Brillouin zone (BZ) that characterize wave behaviors in periodic mediums are two cornerstones of contemporary physics ranging from condensed matter to top…

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…

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…
