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

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

This change in speed can cause the light to bend at the boundary between the two transparent materials. The change in direction of a beam of light as it travels from one material to another is ...

One strategy for identifying domains involves shining a light across the material in one direction and then again in the ...
