Tunable Sound Absorption via Evanescent‐Wave Coupling in Asymmetric Bilayer Metasurfaces
ABSTRACT This study explores tunable sound absorption using a bilayer configuration of phase‐gradient acoustic metasurfaces. By carefully adjusting the cavity length between two metasurface layers, the proposed system can modulate its acoustic response between highly reflective and perfectly absorpt...
