Ultrathin acoustic metamaterial as super absorber for broadband low-frequency underwater sound
Abstract In this work, an ultrathin acoustic metamaterial formed by space-coiled water channels with a rubber coating is proposed for underwater sound absorption. The proposed metamaterial achieves perfect sound absorption ( $$\alpha$$ α > 0.99) at 181 Hz, which has a deep subwavelength thickness (...
