Ultra-Low-Frequency Broadband Sound Absorption Characteristics of an Acoustic Metasurface with Pie-Sliced Unit Cells

Ultra-Low-Frequency Broadband Sound Absorption Characteristics of an Acoustic Metasurface with Pie-Sliced Unit Cells

In this work, an acoustic metasurface composed of pie-sliced resonator segments is proposed and its attenuation characteristics in ultra-low-frequency regime are examined using analytical, numerical, and experimental means. This metasurface absorber is systematically designed and realized with inhom...

Zusammenfassung:In this work, an acoustic metasurface composed of pie-sliced resonator segments is proposed and its attenuation characteristics in ultra-low-frequency regime are examined using analytical, numerical, and experimental means. This metasurface absorber is systematically designed and realized with inhomogeneous unit cells in the shape of sliced pie to accomplish ultra-low-frequency (
