Design and Deep-Subwavelength Low-Frequency Sound Absorption of a Coplanar Spiral-Varying-Channel Acoustic Metamaterial
This study proposes a novel coplanar spiral-varying-channel space-coiled acoustic metamaterial (CSV-SCAM) for efficient low-frequency noise control in the range of approximately 200–400 Hz. By integrating continuously graded spiral channels with secondary spiral branches, the proposed structure enab...
