A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...

High refractive index polymers (HRIPs) are essential for manufacturing modern optoelectronic devices, including displays and light sensors. However, high-performance HRIPs are expensive and ...

(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 ...

Researchers report the development of ultrahigh refractive index metamaterials which are integrated with a low refractive index polymer producing distributed Bragg reflector (DBR). The highest ...

Physicists at Harvard University in the US have built a silicon waveguide that exhibits a refractive index of, or close to, zero when operating at near-infrared telecom wavelengths. The waveguide can ...

A research team develops a transparent silicon without visible light loss by controlling the silicon atomic structure. A POSTECH research team has developed a transparent amorphous silicon that ...

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 ...

The water content of hydraulic brake fluid affects boiling point, viscosity and the corrosive nature of the fluid. Brake overheating can boil fluids containing a significant amounts of water, causing ...

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 ...
