Biomimetic nanostructures for anti-reflection (AR) devices

This chapter highlights natural designs for controlling light and structural coloration in general and anti-reflection (AR) in particular. It is now possible to impart natural functionalities, such as AR from moth eyes or cicada wings, to biomimetic structures. Following these natural clues, we have been able to produce superior AR structures and designs, often in the sub-wavelength scale, to reduce reflectances below 1% over the broad ultraviolet and visible region and achieve an enhanced AR regime in the long wavelength, infrared (IR) and terahertz (THz), part of the spectrum. The chapter will discuss briefly the incorporation of these designs into real applications such as solar cells.
