(a) Reflectance spectra of 40 s Au-coated NAAMs anodized for different lengths of time, (b) versus the anodization time for NAAM (black spheres) and Au/NAAM (blue triangles), (c) minimum reflectance versus , and (d) reflectance spectra of Au/NAAM illuminated with s- and p-polarized light incident at an angle of 45°. The inset shows the dependence of on the wavelength.
