Bifurcation-based acoustic switch and rectifier

摘要: A tunable frequency acoustic rectifier that is a granular crystal composed of statically compressed one-dimensional array particles in contact, containing light mass defect near boundary. The nonlinear and contains pass stop bands their dispersion relation. Vibrations at selected frequencies applied to the from side will cause system bifurcate critical input amplitude subsequently jump quasiperiodic chaotic states with broadband content. Some this content lies within propagate through crystal. same other not bifurcate, little energy transmitted.
