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 ...

What makes it distinct from other metamaterials is that it is made entirely from semiconductor material — the stuff found in computer chips and prized for its ability to act as ...

Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as if defying the law of physics. This phenomenon, known as negative refraction ...

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 bend.

Scientists have unveiled a groundbreaking discovery: a material capable of bending light in unprecedented ways. This advancement opens up possibilities for innovations in optics, including superlenses ...
