Deep learning enables accurate sound redistribution via nonlocal metasurfaces
Hua Ding, Xinsheng Fang, Bin Jia +3
Conventional acoustic metasurfaces are constructed with gradiently ``local'' phase shift profiles provided by subunits. The local strategy implies the ignorance of the mutual coupl…
Observation of higher-order exceptional points in a non-local acoustic metagrating
Xinsheng Fang, Nikhil JRK Gerard, Zhiling Zhou +7
Higher-order exceptional points have attracted increased attention in recent years due to their enhanced sensitivity and distinct topological features. Here, we show that nonlocal…
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…
Engineered diffraction gratings for acoustic cloaking
Yabin Jin, Xinsheng Fang, Yong Li +1
We show that engineered diffraction gratings can considerably simplify the design and performance of acoustic devices. Acoustic reflecting gratings based on rectangular cavities dr…
