Acoustic Vortex Filter Based on Tunable Metasurfaces
Liulin Li, Bingyi Liu, Zhixiang Li +2
In this paper, we present an acoustic vortex filter (AVF) based on tunable metasurfaces, which can selectively filter the incident multiplexed vortices that carry different orbital…

Continuous-wave amplitude control via the interference phenomenon in acoustic structures
Bingyi Liu, Shanshan Liu, Liulin Li +4
We propose a strategy to continuously tune the amplitude of acoustic waves based on the interference among two mode-conversion paths in passive acoustic structures. The interferenc…
