Fig. 1. (Color online) (a) Schematic of the nanodisk array structure. (b) Absorption spectrum for p = 300 nm, d = 100 nm, t = 20 nm. The inset shows electric field enhancement measured at xy-plane at z = -2 nm from the metal-glass interface near the absorption peak. (c) Transmission and reflection spectra for the same structure. (d–f) Same for the complementary nanohole array with the same dimensions.
