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…
Channel-Coupling Fano Resonance and Acoustic Metadamping
Huy Nguyen, Qian Wu, Hui Chen +1
Fano resonance featuring asymmetric spectral profiles originates from the interference of local resonances and background continuum. Its narrow-band nature looks seemingly adverse…
Realization of active metamaterials with odd micropolar elasticity
Yangyang Chen, Xiaopeng Li, Colin Scheibner +2
Materials made from active, living, or robotic components can display emergent properties arising from local sensing and computation. Here, we realize a freestanding active metabea…
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…
Wave propagation in infinite nonlinear acoustic metamaterial beam by considering the third harmonic generation
Xin Fang, Jihong Wen, Dianlong Yu +2
Nonlinear acoustic metamaterial (NAM) initiates new fields for controlling elastic waves. In this work, the flexural wave propagation in the half-infinite NAM beam consisting of pe…
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…
Kirigami-based Elastic Metamaterials with Anisotropic Mass Density for Subwavelength Flexural Wave Control
R. Zhu, H. Yasuda, G. L. Huang +1
A novel design of an elastic metamaterial with anisotropic mass density is proposed to manipulate flexural waves at a subwavelength scale. The three-dimensional metamaterial is ins…
