a A cartoon character “Stitch” (d = 75 nm), b a symbol of Arizona “Cactus” (d = 150 nm), and c a logo of “ASU” (d = 200 nm). Scale bar: 100 μm. d–f AFM measured PPD film thicknesses t for each structure corresponding to (a–c), respectively. g–i FDTD simulated reflectance spectra (dashed lines) and experimentally measured reflectance spectra (solid lines) for each structure corresponding to (a–c), respectively.
