Fig. 5. Diffraction of monochromatic light from 2D nanopattern arrays. Light diffraction from (a) squares (640 nm × 640 nm), (b) rectangles (2.4 μm × 1.8 μm) (c) squares (2.98 μm × 3.04 μm), and (d) rectangles (parallelograms) (5.8 μm × 950 nm). Angle-resolved measurements of diffraction intensity for the diffraction patterns shown in (a–d) respectively. Scale bar = 10 μm.
