Single-sensor and real-time ultrasonic imaging using an AI-driven disordered metasurface
Wei Wang, Jie Hu, Jingjing Liu +5
Non-destructive testing and medical diagnostic techniques using ultrasound has become indispensable in evaluating the state of materials or imaging the internal human body, respect…
Acoustic meta-stethoscope for cardiac auscultation
Zheng-Ji Chen, Jing-Jing Liu, Bin Liang +2
Straight cylindrical stethoscopes serve as an important alternative to conventional stethoscopes whose application in the treatment of infectious diseases might be limited by the u…
Sound non-reciprocity based on synthetic magnetism
Zhaoxian Chen, Zhengwei Li, Jingkai Weng +4
Synthetic magnetism has been recently realized using spatiotemporal modulation patterns, producing non-reciprocal steering of charge-neutral particles such as photons and phonons.…
Remote Water-to-air Eavesdropping through Phase-Engineered Impedance Matching Metasurfaces
Jing-jing Liu, Zheng-wei Li, Bin Liang +2
Efficiently receiving underwater sound remotely from air is a long-standing challenge in acoustics hindered by the large impedance mismatch at the water-air interface. Here we intr…
Efficient, High-purity, Robust Sound Frequency Conversion with a Linear Metasurface
Chengbo Hu, Wei Wang, Jincheng Ni +5
The intrinsic limitation of the material nonlinearity inevitably results in the poor mode purity, conversion efficiency and real-time reconfigurability of the generated harmonic wa…
Experimental Observation of Efficient Nonreciprocal Mode Transitions via Spatiotemporally-Modulated Acoustic Metamaterials
Zhaoxian Chen, Yugui Peng, Haoxiang Li +7
In lossless acoustic systems, mode transitions are always time-reversible, consistent with Lorentz reciprocity, giving rise to symmetric sound manipulation in space-time. To overco…
A General Method to Design Acoustic Higher-Order Topological Insulators
An-Yang Guan, Zhang-Zhao Yang, Xin-Ye Zou +1
Acoustic systems that are without limitations imposed by the Fermi level have been demonstrated as significant platform for the exploration of fruitful topological phases. By surro…
Acoustic manipulation through zero-thickness perforated plane with strong-coupling effects
Liu-Ming Hao, Xin-Ye Zou, Bin Liang +1
How to manipulate acoustic waves through thinner structures is always a challenging problem due to the linear proportional relationship between the structural thickness and the aco…
Ultrathin acoustic parity-time symmetric metasurface cloak
Hao-Xiang Li, Maria Rosendo-Lopez, Yi-Fan Zhu +5
Invisibility or unhearability cloaks have been made possible by using metamaterials making light or sound flow around obstacle without the trace of reflections or shadows. Metamate…
Omnidirectional Ventilated Acoustic Barrier
Hai-long Zhang, Yi-fan Zhu, Bin Liang +3
As an important problem in acoustics, sound insulation finds applications in a great variety of situations. In the existing schemes, however, there has always been a tradeoff betwe…
Spatial filtering of audible sound with acoustic landscapes
Shuping Wang, Jiancheng Tao, Xiaojun Qiu +1
Acoustic metasurfaces manipulate waves with specially designed structures and achieve properties that natural materials cannot offer. Similar surfaces work in audio frequency range…
Twisted Acoustics
Xue Jiang, Bin Liang, Jian-chun Cheng +1
We use metasurfaces to enable acoustic orbital angular momentum (a-OAM) based multiplexing in real-time, postprocess-free and sensor-scanning-free fashions to improve the bandwidth…
