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 ...
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 sought ...
Photo-thermo-refractive (PTR) glass is a photosensitive multi-component silicate matrix incorporating halides and metal dopants. Upon exposure to ultraviolet or ultrafast laser light and subsequent ...
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 ...
