A skier in Austria captured a stunning sun pillar, a rare optical phenomenon where ice crystals reflect sunlight, creating a ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays—without the ...

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 ...

The allure of negative refraction lies in its groundbreaking potential applications, such as creating a perfect lens capable of focusing and imaging beyond the diffraction limit or developing ...

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...

Scientists have found a way to achieve negative refraction—where light bends the "wrong" way—using carefully arranged atomic ...
