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…
