Ultra‐broadband sound absorption characteristics in underwater ultra‐thin metamaterial with three layer bubbles

Abstract The interest of this article is to obtain the underwater broadband sound absorption characteristics by filling three layers of bubbles in Polydimethylsiloxane polymer (PDMS). In this underwater ultra‐thin metamaterial, three‐layer bubbles are arranged from small to large with the same radiu...
