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 ...

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 ...

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 ...

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 ...

Quantum mechanics theory predicts that, in addition to exhibiting particle-like behavior, particles of all sizes can also ...

A study led by University of Oxford and Brookhaven National Laboratory researchers has uncovered how exposure to hydrogen ...

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 ...

To the recording studio to study interference and diffraction of sound waves. Unit 6 Segment D: Sound: Diffraction and Interference We head back to the recording studio to study interference and ...

Through pioneering contributions that have expanded the capabilities of a class of specialized instruments that use neutrons to probe materials, Charles Majkrzak has given researchers around the world ...
