Using 3D metal-printing topological materials to manipulate full-vector elastic waves

A collaboration between Prof. Weiying Deng at South China University of Technology, Prof. Feng Li at Beijing Institute of Technology, and Prof. Zhengyou Liu at Wuhan University was recently published online in National Science Review. There is growing interest in elastic waves manipulated by topological edge modes, which have unparalleled advantages such as lower energy dissipation, higher flexibility and unidirectional transmission.
