There are many glorious science-based terms when it comes to surfing. We all talk about swells, of course, the underwater energy that creates a breaking wave. But we'll look at swell angles and ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

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

The work was published in Science ("Gate-tunable negative refraction of mid-infrared polaritons"). Basic principle of the “polariton transistor”. The van der Waals heterostructure is constructed by ...
