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…
Reducing symmetry in topology optimization of two-dimensional porous phononic crystals
Hao-Wen Dong, Yue-Sheng Wang, Yan-Feng Wang +1
In this paper we present a comprehensive study on the multi-objective optimization of two-dimensional porous phononic crystals (PnCs) in both square and triangular lattices with th…
Bandgaps and directional propagation of elastic waves in two-dimensional square zigzag lattice structures
Yan-Feng Wang, Yue-Sheng Wang, Chuanzeng Zhang
In this paper we propose some kinds of two-dimensional square zigzag lattice structures and study their bandgaps and directional propagation of elastic waves. The band structures a…
Two-dimensional ternary locally resonant phononic crystals with a comblike coating
Yan-Feng Wang, Yue-Sheng Wang, Litian Wang
Two-dimensional ternary locally resonant phononic crystals used to consist of cylindrical scatterers with uniform coatings in their exterior. An alternative coating scheme with a c…
