Researchers at the University of Hong Kong demonstrate negative light refraction with the natural magnetic material CrSBr – ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as ...

Horiba has developed a particle size distribution measuring device that accurately measures particle size distribution even in the presence of similar-shaped particles. The device uses image ...

IN preparing an elementary lecture on Light, intended to be given at the Taunton College School, I have had to consider how best to explain the somewhat abstruse principle of optical refraction. It is ...
