Negative refraction of light using atoms instead of metamaterials Date: February 14, 2025 Source: Lancaster University Summary: Scientists have demonstrated that negative refraction can be ...

Their work demonstrates that the cooperative response of atoms can enable negative refraction, eliminating the need for metamaterials altogether.

Refraction—the bending of light as it passes through different media—has long been constrained by physical laws that prevent independent control over how light waves along different directions ...
