An Ultra-Thin Composite Metasurface with Hybrid-Damping Modes for Broadband Sound Absorption
In this paper, we proposed an ultra-thin composite metasurface for broadband sound absorption, in which a compound Helmholtz structure and porous materials are coupled in a parallel-series arrangement. The Helmholtz structure comprises multiple compound cells with hybrid-damping modes, in which the...
