Non-zero Integral Spin of Acoustic Vortices and Spin-orbit Interaction in Longitudinal Acoustics
Wei Wang, Yang Tan, Jingjing Liu +2
Spin and orbital angular momenta (AM) are of fundamental interest in wave physics. Acoustic wave, as a typical longitudinal wave, has been well studied in terms of orbital AM, but…
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…
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…
Experimental Realization of Weyl Exceptional Rings in a Synthetic Three-Dimensional Non-Hermitian Phononic Crystal
Zheng-wei Li, Jing-jing Liu, Ze-Guo Chen +5
Weyl points (WPs) are isolated degeneracies carrying quantized topological charges, and are therefore robust against Hermitian perturbations. WPs are predicted to spread to the Wey…
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…
