Waves over a periodic progressive modulation: A python tutorial
Hussein Nassar, Andrew N. Norris, Guoliang Huang
This chapter presents a selection of theoretical and numerical tools suitable for the study of wave propagation in time-dependent media. The focus is on one-dimensional spring-mass…
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…
Physical rendering of synthetic spaces for topological sound transport
Hui Chen, Hongkuan Zhang, Qian Wu +5
Synthetic dimensions can be rendered in the physical space and this has been achieved with photonics and cold atomic gases, however, little to no work has been succeeded in acousti…
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…
Microtwist elasticity: A continuum approach to zero modes and topological polarization in Kagome lattices
Hussein Nassar, Hui Chen, Guoliang Huang
The topologically polarized isostatic lattices discovered by Kane and Lubensky (2014, Nat. Phys. 10, 39-45) challenged the standard effective medium theories used in the modeling o…
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…
