There are two classes of phononic structures that can support elastic waves with non-conventional topology, namely intrinsic and extrinsic systems.The Notebooks/Notepads 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 s
