3D-printed acoustic metasurface with encapsulated micro-air-bubbles for frequency-selective manipulation
Miaomiao Ji, Yukai Liu, Zheng Zhang, Rui Xu, Fanyun Pan, Ya Zhang, Rouyu Su, Minghui Lu, Xiujuan Zhang, Guanghui WangA low-frequency acoustic metasurface with PDMS-stabilized microbubbles achieves stable vibration modes, precise control over micro-object aggregation, rotation, separation, and selective trajectory manipulation through frequency-tuned excitation.
