Calculated spectra of three two-dimensional (2-D) distributions of plasmonic NPs whose polarizability is presented in Fig. 2 (h ≫ a). Panels on (a) show the 2-D susceptibility for ξ=0 (random gas), ξ=20 (short-range clustering), and DLA. The number of particles is the same in all cases. Panels on (b) show the reflectance, transmittance, and absorbance of the corresponding films placed on top of a medium with 1=1.0 and 2=5.0.

Panels on (a) show the real and imaginary parts of the effective dielectric function for ξ=0 (random gas), ξ=20 (short-range clustering), and DLA. The number of particles is the same in all cases. Panels on (b) show the reflectance, transmittance, and absorbance of the corresponding films (of thickness 300 nm) on an SiO2 substrate.
