Light scattering as the basis for size determination of many objects has been explored for a long time. It was Gustav Mie, author of the Mie Scattering Theory, who studied gold nanoparticles in ...

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 ...

What are metamaterials and what can they do? The prefix meta (a Greek word meaning ‘beyond’) indicates that the characteristics of the material are beyond what we see in nature. Metamaterials are a ...
