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 ...

Diffraction spikes, visible in high-power astronomical images, are an intrinsic optical phenomenon in reflecting telescopes, primarily caused by the diffraction and subsequent interference of incoming ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

You can’t put a square peg in a round hole. But putting a square aperture on a round telescope might be the best way to see the light of distant, Earth-like planets. At least, that’s what computer ...
