Discrete metasurface for extreme sound transmission through water-air interface
Shao-Cong Zhang, Hong-Tao Zhou, Xiao-Tong Gong +2
The mismatch of acoustic impedance at water-air interface can lead a low transmitted sound energy. In this paper, we propose a discrete metasurface for extreme sound transmission b…
Quasinormal mode representation of radiating resonators in open phononic systems
Vincent Laude, Yan-Feng Wang
Open phononic systems including resonators radiating inside an unbounded medium support localized phonons characterized by a complex frequency. In this context, the concept of elas…
Effective anisotropy of periodic acoustic and elastic composites
Vincent Laude, Julio Andres Iglesias Martinez, Yan-Feng Wang +1
The propagation of acoustic or elastic waves in artificial crystals, including the case of phononic and sonic crystals, is inherently anisotropic. As is known from the theory of pe…
Broadband inverted T-shaped seismic metamaterial
Yi Zeng, Shu-Yan Zhang, Hong-Tao Zhou +6
Seismic metamaterials (SMs) are expected to assist or replace traditional isolation systems owing to their strong attenuation of seismic waves. In this paper, a one-dimensional inv…
Longitudinal near-field coupling between acoustic resonators grafted onto a waveguide
Yan-Feng Wang, Vincent Laude
We investigate longitudinal near-field coupling between acoustic resonators grafted onto a waveguide. Experiments are performed in the audible range with a simple acoustic system c…
