Metasurface optical antireflection coating [PDF]
Applied Physics Letters, 2014 Light reflection at the boundary of two different media is one of the fundamental phenomena in optics, and reduction of reflection is highly desirable in many optical systems. Traditionally, optical antireflection has been accomplished using single- or multiple-layer dielectric films and graded index surface structures in various wavelength ranges ...

Ultra-antireflective synthetic brochosomes [PDF]
Nature Communications, 2017 AbstractSince the early discovery of the antireflection properties of insect compound eyes, new examples of natural antireflective coatings have been rare. Here, we report the fabrication and optical characterization of a biologically inspired antireflective surface that emulates the intricate surface architectures of leafhopper-produced brochosomes ...

Wave propagation in highly inhomogeneous thin films : exactly solvable models [PDF]
, 2005 We present an exact treatment of wave propagation in some inhomogeneous thin films with highly space-dependent dielectric constant. It is based on a space transformation which replaces the physical space by the optical path.
