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.
