Multi-states in the bandgap of NAM plate. Frequency is 760 Hz. a Response amplitudes v rsp at points A and B varying against the linearly and continuously varied driving amplitude v ex in time domain, i.e., the varying-amplitude experiment (see Methods). In the legend, Increase (decrease) refers to the process increasing (decreasing) v ex. Black arrows show the varying routes. b Contour plot of the transmission difference ΔT v between v e1 = 3.13 and v e2 = 8.55 labeled in a, ΔT v = T v2T v1. Scanning experiments were carried out to obtain this plot
