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 ...

Scientists have long sought to control light in ways that appear to defy the laws of Nature. Negative refraction - a phenomenon where light bends in the opposite direction to its usual behaviour ...

The change in direction of a beam of light as it travels from one material to another is called refraction. The normal is a construction line drawn at right angles to the surface of the glass block.

A ray diagram showing refraction at the boundary between air and glass Refraction can cause optical illusions as the light waves appear to come from a different position to their actual source.

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially ...
