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…
Elastic quantum spin-Hall effect in Kagome lattices
Hui Chen, Hussein Nassar, Andrew N. Norris +2
A Quantum Spin-Hall Insulator (QSHI) is implemented into a simple mass-spring Kagome lattice. The transition from the trivial state to the topological one is described by an invari…
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…
Topological mechanics of edge waves in Kagome lattices
Hui Chen, Hussein Nassar, Guoliang Huang
Topological insulators are new phases of matter whose properties are derived from a number of qualitative yet robust topological invariants rather than specific geometric features…
