One-Dimensional Mass-Spring Chains Supporting Elastic Waves with Non-Conventional Topology
Fats 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 wave propagation.In extrinsic systems, energy is injected into the phononic structure to br
