Low angle dependence of Model I.
(a) contour plot showing reflections versus wavelength and incident angle for Model I (the color-coded intensities correspond to a linear scale); (b–d) contour plot showing reflections versus viewing angle and wavelength for Model I at incident angles of 0°, 30° and 60° (the color-coded intensities correspond to a logarithmic scale); and (e–g) electric field intensity contour plot for Model I for incident angles of 0°, 30° and 60° and a wavelength of 440 nm (the color-coded intensities correspond to a linear scale); x and y are defined in Figure 1.
