Broadband sound barriers with bianisotropic metasurfaces

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, bandw...
