Regulation of high-frequency vibrations via phononic crystal structure with zero Poisson’s ratio
AIP AdvancesVibration affects the service life of engineering structures and the working accuracy of instruments, causing engineering accidents such as structural collapse and equipment explosion. Phononic crystals can effectively suppress the propagation of elastic

One-Dimensional Mass-Spring Chains Supporting Elastic Waves with Non-Conventional Topology
Crystals, 2016 There are two classes of phononic structures that can support elastic waves with non-conventional topology, namely intrinsic and extrinsic systems. The non-conventional topology of elastic wave results from breaking time reversal symmetry (T-symmetry) of
