When a pulse of light reflects from a mirror that is travelling close to the speed of light, Einstein’s theory of relativity predicts that it will be up-shifted to a substantially higher frequency and ...

The collective response of charged particles to intense fields is intrinsic to plasma accelerators and radiation sources, relativistic optics and many astrophysical phenomena. Here we show that a ...

Test for echo: schematic diagram of an object to be imaged (blue blob) and illumination source (concentric circles) inside a randomly shaped cavity. The detector is represented by the two parallel ...

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 ...

Distinguished for his pioneering studies in X-ray diffraction physics, especially for his development of the technique of X-ray topography, Andrew Lang will be greatly missed by many researchers for ...

Although electron backscatter diffraction (EBSD) was first discovered by Kikuchi in 1928, its potential for microstructural characterization became fully realized only after the technique was ...

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 ...
