An asymmetric elastic metamaterial model for elastic wave cloaking
Hongkuan Zhang, Yi Chen, Xiaoning Liu +1
Elastic material with its elastic tensor losing minor symmetry is considered impossible without introducing artificially body torque. Here we demonstrate the feasibility of such ma…

Boundary effect on acoustic cloak with unideal pentamode material
Yi Chen, Xiaoning Liu, Gengkai Hu
Pentamode materials are elastic solids with vanishing shear modulus, and can be used cloak underwater sound with solid state and broadband merits. However, pentamode materials real…

Longitudinal elastic wave control by pre-deforming semi-linear materials
Dengke Guo, Yi Chen, Zheng Chang +1
An incremental wave superimposed on a pre-deformed hyper-elastic material perceives an elastic media with the instantaneous modulus of the current material. This offers a new route…
