Topological resonance behaviors of surface acoustic wave under surface liquid-layer loadings and sensing applications

Autor: Wu, Bowei, Ma, Tingfeng, Li, Shuanghuizhi, Su, Boyue, Kang, Pengfei

In this work, topological resonance behaviors of surface acoustic wave (SAW) under surface liquid-layer loadings are investigated. The results show that through the coupling of waveguide and resonant cavity, a resonant peak with high Q-factor can eme

Evolution of static to dynamic mechanical behavior in topological nonreciprocal robotic metamaterials

Autor: Tang, Zehuan, Ma, Tingfeng, Chen, Hui, Gao, Yuanwen

Based on the Maxwell-Beatty reciprocity theorem, static non-reciprocity has been realized by using nonlinearity, but this non-reciprocity has strict restrictions on input amplitude and structure size (number of units). Here, we propose a robotic meta

Anomalous size effects of effective stiffnesses in bistable counter-rotating mechanical metamaterials

Autor: Tang, Zehuan, Ma, Tingfeng, Su, Boyue, Kang, Pengfei, Wu, Bowei, Chen, Hui, Li, Shuanghuizhi, Wu, Decai, Zhang, Yujie, Zhao, Gen

Counter-rotating mechanical metamaterials have previously been found to have anomalous characteristics or functions such as auxetics effects, shape changers, and soliton transports, which are all under monostable conditions. The properties of counter

Elastic fractal higher-order topological states

Autor: Ma, Tingfeng, Wu, Bowei, Xu, Jiachao, Chen, Hui, Li, Shuanghuizhi, Su, Boyue, Kang, Pengfei, Wang, Ji

Fractal is an intriguing geometry with self-similarity and non-integer dimensions, the elastic-wave topological phase based on fractal structures has not been revealed up to now. In this work, elastic-wave higher-order topological states in fractal s
