Bilayer ventilated labyrinthine metasurfaces with high sound absorption and tunable bandwidth
Abstract The recent advent of acoustic metamaterials offers unprecedented opportunities for sound controlling in various occasions, whereas it remains a challenge to attain broadband high sound absorption and free air flow simultaneously. Here, we demonstrated, both theoretically and experimentally,...
