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 ...

By combining two fundamentally different microscopy techniques, researchers can now measure the optical properties of a ...

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

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 ...

Microscopic crystals in tantalum disulfide have a starring role in what could become a hit for 3D displays, virtual reality and even self-driving vehicles. Microscopic crystals in tantalum disulfide ...

Discover how ice crystals and winter skies create sundogs, sun pillars and halos — and when to look up from the Nature Center ...

Here, a calcite crystal is struck with a laser operating at 445 nanometers, fluorescing and displaying properties of birefringence. Unlike the standard picture of light breaking into individual ...
