Although we generally assume that opacity is the normal look for animals like us humans, this factoid is only correct for as long as you maintain the dissimilar optical refraction indices of skin and ...

A superlattice comprising alternating layers of negative-refractive-index photonic crystals and positive-refractive-index dielectric media has been shown to exhibit an effective refractive index of ...

To measure the refractive index distribution in porcine eye lenses for two wavelengths from the visible spectrum: 532 and 633 nm, in order to determine whether there are any discernible wavelength ...

The refractive index of a material defines the angle through which light is bent when it travels between a material and the vacuum. Ordinary materials such as glass have refractive indices between one ...

There has been interest in the Negative Refraction Index (NRI) material at optical frequencies. There are two approaches to optical frequencies. 1)Volumetric structure: it is based on the spherical ...

(Nanowerk News) This will potentially allow them to create more compact and efficient elements for lasers, sensors, and optical chips. Moreover, it proves the hypothesis that ITMO physicists had about ...

Bulletin of the American Meteorological Society, Vol. 37, No. 6 (June, 1956), pp. 251-262 (12 pages) The study of tropospheric refractive index distributions which began in 1951 using an airborne ...

Toyohashi University of Technology researchers in collaboration with Massachusetts Institute of Technology (MIT), have developed a new material capable of retaining high transmissivity after thermal ...

High index lenses are glasses lenses that are thinner and lighter than standard options. They may benefit people with stronger prescriptions who might otherwise have heavier, thicker lenses. Share on ...

Among the various sensing modalities available for bioprocess operations, index of refraction (IoR) is intriguing for its simplicity and capability for sample-less, real-time readout. A group led by ...
