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 ...

If you studied advanced physics at high school, there's a good chance that you remember Snell's law, which states how a ray of light bends when it crosses a boundary between two media. According to ...

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 ...

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

High-Index Lenses Types Depending on the prescription, you will need to use a different index. The index of refraction is determined by how fast light can move through a particular material. The more ...

In spooky season fashion, we are going to bring magic to this episode of Up and Atom. Well, science disguised as magic.

A computational design study reports a compact photonic crystal nanocavity biosensor that detects refractive-index changes ...
