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 ...

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 ...

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 ...

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 ...

I. Positive (normal) dispersion. This is what happens in most light-matter interaction. The medium has higher index of refraction for higher frequencies; the frequency components of a pulse are ...

Researchers at Harvard University, working with collaborators at the University of Lisbon, discovered that low-index silica ...

Capasso himelf called the discovery “a counterintuitive breakthrough in nanotechnology.” He added, “We have demonstrated in ...
