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.…
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…
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…
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…
