Physicists are involved in an unusually heated debate over the reality of a new kind of refraction and about the possibility of making perfect lenses. Edwin Cartlidge reports. If you think science is ...

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 ...

The alternative text for this image may have been generated using AI. In this Letter, we experimentally demonstrate nonlinear optical negative refraction in thin metallic nanostructures. We use a ...

Geometric optics explains how light behaves when it reflects, refracts, and forms images through lenses and mirrors. From total internal reflection in fiber optics to the sparkle of rainbows, these ...

Most people know that light travels in a straight line unless something acts upon it to change its direction. The three most common methods of changing the direction of light are refraction, ...
