A passively tunable non-resonant acoustic metamaterial lens for selective ultrasonic excitation
Hongfei Zhu, Fabio Semperlotti
In this paper, we present an approach to ultrasonic beam-forming and beam-steering in structures based on the concept of embedded non-resonant acoustic metamaterial lenses. The len…
