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 first law of refraction states that the incident rays, refracted rays, and the normal to the interface at the point of incidence, all lie in the same plane. The ratio of the sine of the angle of ...

Figure 1: Analytical study of one-dimensional chains of resonant point scatterers. Starting from this unit cell that creates the single negative property, we build two new configurations just by ...

Light energy travels in straight lines and in waves. Light energy travels in straight lines and in waves. When light strikes a plane or a flat surface, it reflects in a manner that is predictable. For ...

Researchers in Korea have created a new metamaterial with the most extreme positive index of refraction yet – a whopping 38.6. The metamaterial operates at terahertz frequencies and the team believes ...

Science presenter Jon Chase explains the refraction of light. He demonstrates how refraction can make the handle of a glass jug seemingly disappear.
