From: Interdisk spacing effect on resonant properties of Ge disk lattices on Si substrates
Normalized reflectance for arrays with different numbers of disks: (a) infinite, (b) 21 × 21. The structure was irradiated with a plane wave in (a) and with a highly divergent Gaussian beam, which can be formed by an objective with NA = 0.65 in (b). The disks were 200 nm in diameter and 120 nm high. The G values are marked in the figures. The dispersions of n and k for Si and Ge used in the simulation are shown in the inserts in (a,b), respectively.
