Flexural wave illusion on a curved plate
Pengfei Zhao, Liyou Luo, Yongquan Liu +1
Manipulating elastic waves using a transformation approach is challenging due to the complex constitutive relationship. However, for flexural waves, approximated as scalar waves, t…
Meta-fences: blocking waves utilizing a layer of identical tiny scatters
Yunhao Zhang, Zhendong Sha, Guangyuan Su +6
Wave steering by artificial materials (for example, phononic crystals and acoustic metamaterials) is a fascinating frontier in modern physics and engineering, but suffers from bulk…
Steering Flexural Waves by Amplitude-Shift Elastic Metasurfaces
Guangyuan Su, Yunhao Zhang, Yongquan Liu +1
As 2D materials with subwavelength structures, elastic metasurfaces show remarkable abilities to manipulate elastic waves at will through artificial boundary conditions. However, t…
Efficient asymmetric transmission of elastic waves in thin plates with lossless metasurfaces
Bing Li, Yabin Hu, Jianlin Chen +4
Requiring neither active components nor complex designs, we propose and experimentally demonstrate a generic framework for undistorted asymmetric elastic-wave transmission in a thi…
Willis metamaterial on a structured beam
Yongquan Liu, Zixian Liang, Jian Zhu +5
Bianisotropy is common in electromagnetics whenever a cross-coupling between electric and magnetic responses exists. However, the analogous concept for elastic waves in solids, ter…
Source illusion devices for flexural Lamb waves using elastic metasurfaces
Yongquan Liu, Zixian Liang, Fu Liu +3
Metamaterials with the transformation method has greatly promoted the development in achieving invisibility and illusion for various classical waves. However, the requirement of ta…
