Abstract

Recently we performed a numerical investigation of antireflection coatings that reduce significantly the reflection over a wide range of wavelengths and angles of incidence, and we proposed some experiments to demonstrate their feasibility. We provide a theoretical description of omnidirectional antireflection coatings that are effective over a wide range of wavelengths.

  15. It is worth noting that when the ratio ηmax/ηmin under the exponent in Eq. (7) is increased, the profile of the ES transition layer becomes similar to the modified profile [Fig. 7(d1)].
  16. It may be preferable to use an uneven distribution of points, since (i) its effect on the performance at short wavelengths and large angles of incidence is not critical and (ii) because many layers with close indices would be hard to achieve in practice.
