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…
Broadband solid cloak for underwater acoustics
Yi Chen, Mingye Zheng, Xiaoning Liu +5
Application of transformation theory to underwater acoustics has been a challenging task because highly anisotropic density is unachievable in water. A possible strategy is to expl…
Design Omnidirectional Wave Absorbers by Transformation Method
Zheng Chang, Gengkai Hu
A general conformal mapping is proposed to design omnidirectional broadband wave absorbers by transformation method. When applied to electromagnetic (EM) and acoustic waves, the ex…
Transformation Ray Method: Controlling High Frequency Elastic Waves
Zheng Chang, Jin Hu, Xiaoning Liu +1
A transformation method based on elastic ray theory is proposed to control high frequency elastic waves. We show that ray path can be controlled in an exact manner, however energy…
