Figure 6

Experimental characterization of the Bloch oscillations of torsional waves propagating in a chirped structure with γ = 0.06. (a) Oscillatory behavior observed for a wave packet centered at fC = 14.5 kHz. (b) Oscillations corresponding to a packet with fC = 15 kHz. The horizontal red lines define the interface between the uniform and structured parts of the beam, which is schematically drawn on the right-hand side. The color scale defines the amplitude of displacement (in arbitrary units).
