Subwavelength Chiral Spiral Acoustic Metamaterials for a Robust Topological Acoustic Insulator
Topological acoustic insulators enable sound waves to transmit along the surface without backscattering, which builds a new pathway towards sound wave control. However, a large share of topological acoustic insulators are realized based on special point group symmetry and Bragg scattering mechanism....
