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 ...

University of Central Florida researchers have developed a new type of laser beam that doesn't follow long-held principles about how light refracts and travels. The findings, which were published ...
