Figure 3. The FDTD simulations of spatial distributions of the electric field, E2 for the three wavelengths in Figure 3b.

(a,b) correspond to the wavelengths at 493 and 524 nm, respectively, in Green_3. The strongest travelling mode seen in the PMMA/LOR pillar in (a) is responsible for the reflection dip at 493 nm in the spectra (both the red and the blue line) in figure 3b. The relatively weak E² in the multilayer in (b) (524 nm) and (c) (532 nm) explains the high reflection in the spectra. The dash lines highlight the lamellae structures.
