Discrete Transformation Elasticity: An Approach to Design Lattice-based Polar Metamaterials
Yangyang Chen, Hussein Nassar, Guoliang Huang
The transformation method is a powerful tool for providing the constitutive parameters of the transformed material in the new coordinates. In transformation elasticity, a general c…
Polar metamaterials: A new outlook on resonance for cloaking applications
H. Nassar, Y. Y. Chen, G. L. Huang
Rotationally resonant metamaterials are leveraged to answer a longstanding question regarding the existence of transformation-invariant elastic materials and the ad-hoc possibility…
Observation of nonreciprocal wave propagation in a dynamic phononic lattice
Yifan Wang, Behrooz Yousefzadeh, Hui Chen +3
Acoustic waves in a linear time-invariant medium are generally reciprocal; however, reciprocity can break down in a time-variant system. In this Letter, we report on an experimenta…
