Fig. 2: Mean path lengths with respect to the number of scatterers.
From: Mean path length invariance in wave-scattering beyond the diffusive regime
a Mean path length evaluated as 〈s(2Qt)〉, see Eq. (1), obtained in simulations without (black crosses) and with (black circles) absorption as a function of the number of metallic cylinders within the cavity. The red solid line is the theoretical length calculated from the Weyl law (see Eq. (2)). Absorption reduces the estimated mean path length. Background colors in rose, green, and white mark the localized, diffusive, and the ballistic regime as in Fig. 1b. b The same quantity, 〈s(2Qt)〉, found experimentally (blue circles). The squares and triangles are the mean path length in transmission and in reflection, respectively (see Supplementary Note 1 for details). Error bars represent the standard deviation.
