Figure 3.

(a) Experimental (black line) and FDTD transmission spectrum (red) of a glass/perforated Ag electrode (height = 100 nm, diameter = 200 nm, pitch = 400 nm)/TiO₂ (h = 17 nm)/polymer (220 nm)/air dielectric stack. Normalized field intensity distributions, |E|²/|E ₀|² for light with (b) λ = 927 nm and (c) λ = 1020 nm. In (b) and (c), the glass spans from z = −0.2 μm to z = 0 μm, the Ag MHA spans from z = 0 μm to z = 0.1 μm (and the hole in the Ag layer spans from x = −0.1 μm to x = 0.1 μm), the TiO₂ layer spans from z = 0.1 μm to z = 0.117 μm, and the polymer layer spans from z = 0.117 μm to z = 0.337 μm.
