Extreme Low-Frequency Ultrathin Acoustic Absorbing Metasurface
Krupali Donda, Yifan Zhu, Shi-Wang Fan +3
We introduce a multi-coiled acoustic metasurface providing a quasi-perfect absorption (reaching 99.99% in experiments) at extremely low-frequency of 50 Hz, and simultaneously featu…
Highly efficient acoustic refractive metasurfaces by harnessing near field coupling
Zhilin Hou, Xinsheng Fang, Yong Li +1
Typical acoustic refractive metasurfaces governed by generalized Snell law require several types of subwavelength subunits to provide an extra phase gradient along the surface. Thi…
Perfect anomalous splitter by acoustic meta-grating
Huiqin Ni, Xinsheng Fang, Zhilin Hou +2
As an inversely designed artificial device, metasurface usually means densely arranged meta-atoms with complex substructures. In acoustics, those meta-atoms are usually constructed…
Extremely asymmetrical acoustic metasurface mirror at the exceptional point
Xu Wang, Xinsheng Fang, Dongxing Mao +2
Previous research has attempted to minimize the influence of loss in reflection- and transmission-type acoustic metasurfaces. This letter shows that, by treating the acoustic metas…
