Figure 8: Blue lines report the transmission diagrams already presented in Figure 5 in logarithmic scale, whereas red lines display on the same scale the results obtained by the equivalent structures with the parameters listed in Table 1. The angles of incidence of the input light for the original arrays are (a) θ = 5°, (b) θ = 10°, and (c) θ = 15°.
