Tunable acoustic energy concentrations based on pseudo-spin locking waveguides and topological rainbow trappings
Bowei Wu, Teng Wang, Shuanghuizhi Li +1
In this work, tunable acoustic energy concentrations are realized based on pseudo-spin locking waveguides and topological rainbow trappings. Firstly, a tunable pseudo-spin locking…
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…
Topological resonance behaviors of surface acoustic waves under a surface liquid-layer loading and sensing applications
Bowei Wu, Tingfeng Ma, Shuanghuizhi Li +7
In this work, topological resonance behaviors of surface acoustic waves (SAW) under a surface liquid-layer loading are investigated. By revealing influences of the liquid-layer loa…
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…
