A General Framework of Bound States in the Continuum in an Open Acoustic Resonator
Lujun Huang, Bin Jia, Artem S Pilipchuk +11
Bound states in the continuum (BICs) provide a viable way of achieving high-Q resonances in both photonics and acoustics. In this work, we proposed a general method of constructing…
Experimental Verification of the Acoustic Geometric Phase
Bingyi Liu, Zhiling Zhou, Yongtian Wang +3
The optical geometric phase encoded by the in-plane spatial orientation of microstructures has promoted the rapid development of numerous new-type optical meta-devices. However, pu…
Topological Supercavity Resonances In the Finite System
Lujun Huang, Bin Jia, Yan Kei Chiang +7
Acoustic resonant cavities play a vital role in modern acoustical systems. They have led to many essential applications for noise control, biomedical ultrasonics, and underwater co…
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…
Sound Trapping in an Open Resonator
Lujun Huang, Yan Kei Chiang, Sibo Huang +7
The ability of extreme sound energy confinement with high-quality factor (Q-factor) resonance is of vital importance for acoustic devices requiring high intensity and hypersensitiv…
Ultra-broadband acoustic ventilation barriers via hybrid-functional metasurfaces
Ruizhi Dong, Dongxing Mao, Xu Wang +1
Ventilation barriers allowing simultaneous sound blocking and free airflow passage are of great challenge but necessary for particular scenarios calling for sound-proofing ventilat…
Low-frequency broadband acoustic metasurface absorbing panels
Jun Ji, Dongting Li, Yong Li +1
A broadband sound absorption attained by a deep-subwavelength structure is of great interest to the noise control community especially for extremely low frequencies (20-100 Hz) in…
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…
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…
Simultaneous Observation of Topological Edge State and Exceptional Point in an Open and Non-Hermitian System
Weiwei Zhu, Xinsheng Fang, Dongting Li +4
This paper reports on the experimental observation of topologically protected edge state and exceptional point in an open and Non-Hermitian system. While the theoretical underpinni…
Experimental realizations of full control of reflected waves with subwavelength acoustic metasurfaces
Yong Li, Xue Jiang, Rui-qi Li +4
Metasurfaces with subwavelength thickness have exhibited unconventional phenomena in ways that could not be mimicked by traditional materials. Here we report the analytical design…
