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 ...

The interaction between electromagnetic waves and plasma is a subject of considerable interest due to its relevance in aerospace, telecommunications, and stealth technologies. When electromagnetic ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
