Fig. 8From: Dichroic Optical Diode Transmission in Two Dislocated Parallel Metallic GratingsThe influence of Δ on transmission spectra and the isolation contrast ratio. Δ = 50 nm = Λ2/12 (a), Δ = 100 nm = Λ2/6 (b), and Δ = 150 nm = Λ2/4 (c) when d = 200 nm, s = h = 50 nm, Λ1 = 900 nm, and Λ2 = 600 nm. The insets in (b) are Ey distributions for upward transmission resonancesBack to article page
