(a) ξ versus frequency f for ϵ = 0.015 (blue bullets for experiments and blue lines for simulations) and ϵ = 0.040 (red empty symbols for experiments and red lines for simulations) for the periodic case. (b) Same for the random case. Solid-black lines: linear theoretical predictions of Eq. (4). (c) ξ versus ϵ for a frequency lower (0.7 Hz), larger (1.5 Hz), and within (1.1 Hz) the theoretical band gap for the periodic case. (d) Same for the random case. Error bars are related to the exponential fit error (Fig. 3).
