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…

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…
