Broadband low-frequency sound absorption in open tunnels with deep sub-wavelength Mie resonators
Frontiers in Physics, 2022 We report both experimentally and numerically that near-perfect absorption of low-frequency sound is realized in an open tunnel embedded with two deep sub-wavelength (0.085 λ) Mie resonators. The resonators are composed of a multiple-cavity structure and
