Low acoustic impedance arc-shaped chiral metamaterials for low-frequency and broadband underwater sound insulation

Materials & Design
This work proposes an arc-shaped chiral metamaterial (ACM) for low-frequency underwater sound insulation. The equivalent parameters of the designed arc-shaped chiral lattice (ACL) in the metamaterial are derived and evaluated using homogenization method.

Dynamic characteristics of an acoustic metamaterial with locally resonant microstructures [PDF]

, 2009
Wave propagation in acoustic metamaterials with locally resonant-type microstructures was investigated. Because of their unusual forms of microstructures, these metamaterials, if represented by classical elastic continuous solids, would exhibit unusual ...
