Realization of Friedrich-Wintgen QBIC with high Q-factors based on acoustic-solid coupling and sensing applications
Bowei Wu, BoyueSu, Shuanghuizhi Li +1
In recent years, bound states in the continuum (BICs) have attracted extensive attentions in the sensing field due to their theoretically ultra-high resonance quality factors (Q-fa…
Particle manipulations based on acoustic valley topological rainbow defect-state trapping
Decai Wu, Bowei Wu, Tingfeng Ma +5
Acoustic microfluidic is an important technology in particle manipulations in biomedical analyses and detections. However, the particle-movement manipulations achieved by the stand…
Anomalous size effects with fixed criticality in bistable flexible mechanical metamaterials
Zehuan Tang, Tingfeng Ma, Boyue Su +3
When the structure deformation is dominated by the low-energy deformation mode, the structure hardens with the increase in the size (number of units) at small sizes. This anomalous…
Elastic fractal higher-order topological states
Tingfeng Ma, Bowei Wu, Jiachao Xu +5
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. I…
