The Acoustic Metasurface and its Absorption Coefficient

Caption

(Left) The metasurface composed of a perforated plate (transparent gray region) with a hole and a coiled coplanar air chamber (yellow region). (right) The absorption coefficient, α, of the presented metasurface with a total absorption at 125.8 Hz. Results from the impedance analysis and numerical simulations show excellent agreement
