Figure 3

FDTD-simulated S-polarized |E|2 distributions at the y=0 xz plane: (a1–a5) for the D=sqrt(4dt) nodular geometry and (b1–b5) for the D=sqrt(8dt) nodular geometry. The white lines represent film stacks. To better illustrate the |E|2 distributions, the color scale is different for different nodules. FDTD, finite-difference time-domain.
