This is the basic principle behind single-layer anti-reflection coatings first observed by Lord Rayleigh. The ideal refractive index, ni, for such a coating is given by equation (1):(1)ni=n1n2where n1 and n2 are the refractive indices of the existing layers. The refractive indices of air...
Conventional anti-reflection layers are often based on the principle of destructive interference to suppress reflection by stacking alternating transparent dielectrics with high and low refractive indices, with thicknesses of a quarter-wavelength (λ/4n, where n is the refractive index of the ...
According to the famous study of Bernhard and Miller18 in the 1960s, the index of refraction changes gradually in the moth eye due to submicroscopic nipples, and such structuring reduces the reflection of light. In the meantime, this principle has been also found in eyes19 and wings5,6 of...

Principle of structural antireflection. The nanopillars act as a graded index layer on top of the substrate due to their specific shape and size Full size image To achieve the formation of high spatial frequency LIPSS (HSFL) onSiO2surfaces with antireflection properties, several crucial factors must...
used octadecyltriethoxysilane (OTS) as low-surface-energy substance for modified lignocellulose (LC)/SiO2 superhydrophobic coating [51]. The principle is that the breakage and reformation of hydrogen bonds between LC/SiO2–OH and OTS−OH spontaneously and continuously replenish the consumed low-...
An anti-reflection coating anti-reflection coating with low resistivity function and transparent conductive coating as outermost layer is disclosed. The anti-reflection coating contains a transparent conductive
principle an inorganic oxide. Although an inorganic oxide gives a compact and dense film, if a plastic material is used as the substrate, reduction of the heat resistance and adhesion is caused owing to the difference in the coefficient of linear expansion between the coating film and the ...
The term "lithographic process" refers to a process in which a pattern is delineated in a layer of material sensitive to photons, electrons or ions. The principle is similar to that of a photocamera in which an object is imaged on a photo-sensitive emulsion film. While with a photo-camera...
On the other hand, inorganic ARC films are generally based on the principle of destructive interference. This is done by adjusting the optical constants (refractive index n and extinction coefficient k) and the film thickness, such that the exposure radiation that is transmitted through the resist...
