A flash of light has turned a sheet of atoms into a dance floor. In a feat of precision physics, researchers from Cornell and ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

Fundamental diffraction physics says that a larger aperture improves both resolution and penetration. However, aperture size has historically been limited by system complexity and unknown benefit in ...

In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...

The incredible optical characteristics of textured metal films are prompting physicists to rethink the laws of optics. An international team of physicists led by Henri Lezec and Thomas Ebbesen of ...
