Researchers have developed a new type of laser beam that doesn't follow long-held principles about how light refracts and travels. The findings could have huge implications for optical communication ...

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 ...

When light passes through a material, the spatial arrangement of the material’s atoms can cause the light to undergo ...

I am constantly scanning the sky. It’s just what I do. On my commute home from the University of Georgia yesterday, I saw something that always excites me. I quickly grabbed my phone, rolled down the ...
