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…
