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 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…
