Low-frequency sound-absorbing metasurface constructed by a membrane-covered and coiled Helmholtz resonator

Achieving broadband absorption of sound waves below 500 Hz with materials of sub-wavelength thickness is significant but still a great challenge in academia and industries. Here, we present and theoretically analyze an airtight sound-absorbing metasurface constructed by a membrane-covered and coiled...
