Fig. 4: Autocorrelation of calculated near-field intensity maps.

a Color maps of both the electric field and intensity distribution in the y = 0 nm plane for a random illumination pattern. Scale bars represent λ0/neff = 341 nm. b Radial average of the normalized autocorrelation profiles (semi-log scale in the inset). Colored curves correspond to: the homogeneous effective medium obtained by the summation of randomly oriented plane waves (PWs, solid, red), generalized multiparticle Mie theory (GMMT) calculations (solid, green), and GMMT calculations considering only host-medium regions (dashed, green). The black curves represent theoretical predictions for homogeneous media with effective (solid) and host (dashed) refractive index.
