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 ...
By combining two fundamentally different microscopy techniques, researchers can now measure the optical properties of a ...
Utilizing Index of Refraction Monitors in Biopharmaceutical Downstream Processing and Purification When the FDA published the 2003 document, “Pharmaceutical Current Good Manufacturing Practices (CGMPs ...
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 ...
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 ...
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 ...
