Abstract

Journal of Vibration and Control, Ahead of Print.
Efficient broadband noise mitigation by compact absorbers remains a longstanding pursuit in acoustic engineering. Here, a composite phase-gradient acoustic metasurface (AMS) is proposed to achieve broadband and wide-angle sound absorption. The AMS ...
