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

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

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 ...

A material coating, whose light refraction properties can be precisely switched between different states, has been developed by an interdisciplinary research team from the Chemistry and Physics ...

Concept of magnetic order-mediated excitonic negative refraction and schematic of the micro-device. Imagine shining a ...

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 ...
