Broadband sound barriers with bianisotropic metasurfaces, Published online: 13 December 2018; doi:10.1038/s41467-018-07809-3

Methods to silence broadband noise and shield large volumes are lacking. Here, the authors show theoretically and experimentally that acoustic bianisotropic materials, with non-zero strain to momentum coupling, lead to effective sound barriers with excellent efficiency in terms of attenuation, bandwidth, and shielded volume.
