Collective resonant structures. Having provided evidence for the importance of the resonant frequency distribution for determining optical properties, a missing piece is to relate cdf(ω res,i ) to structure. After all, a particular particle's ω res,i is not randomly sampled from cdf(ω res,i ), but rather set by the particle's unique local environment within the disordered and (E) show only "red" nanoparticles with ω res ≤ 0.35ω * p (25% of all nanoparticles), and (C) and (F) show only "blue" nanoparticles with ω res ≥ 0.55ω * p (20% of all nanoparticles). (G)-(I) Structure factor S as a function of wavevector components parallel q ∥ and perpendicular q ⊥ to Ê0 computed among all nanoparticles (G), among only "red" nanoparticles (H), and among only "blue" nanoparticles (I). material. To quantify this, we label nanoparticles by their individual resonant frequency and then examine spatial correlations between particles resonating in similar frequency ranges.
