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 ...

Researchers at Beijing University of Chemical Technology (BUCT) and BOE Technology Group Co., Ltd. (BOE) have developed a novel type of transparent organic–inorganic hybrid photoresist with highly ...

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...

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 ...

The Brix scale, derived from the refractive index of a solution at 20 degrees Celsius (68 Fahrenheit), is widely known. Originally, it was established by determining the weight percentage of sucrose ...

Crystalline arsenic trisulfide shows record photorefractive response and can be laser-patterned at 500-nm resolution without ...
