Phase gradient ultra open metamaterials for broadband acoustic silencing

Abstract Noise pollution is a persistent environmental concern with severe implications for human health and resources. Acoustic metamaterials offer the potential for thin silencing devices; however, existing designs often lack practical openness and are thereby limited by their functional bandwidth...
