Electron beam oscillators utilising surface wave structures represent a key technology in the generation of high‐power electromagnetic radiation. By deploying relativistic electron beams in ...
(Nanowerk News) One of the most fundamental interactions in physics is that of electrons and light. In an experiment at Goethe University Frankfurt, scientists have now managed to observe what is ...
FRANKFURT. It was one of the biggest surprises in the history of science: In the early days of quantum physics around 100 years ago, scholars discovered that the particles which make up our matter ...
X-ray beams aren't used just by doctors to see inside your body and tell whether you have a broken bone. More powerful beams ...
A technical paper titled “Measuring electrical properties in semiconductor devices by pixelated STEM and off-axis electron holography (or convergent beams vs. plane waves).” was published by ...
Plasma waves can experience sudden changes in frequency with drastic effects, which are important to correctly model.
It is found that the reconstruction of the electronic environment and the optimization of the electromagnetic attenuation mechanism are achieved by constructing a model of metal–support interaction ...
Imagine standing by a lake and throwing a stone into the water. Waves spread out in circular patterns and can reflect at ...
Japanese researchers have revealed how weak magnetic fields can instantly control the direction of electrical flow in quantum metals. Quantum metals are materials in which quantum effects, usually ...
Observations during two flybys by the Mio spacecraft as part of the BepiColombo International Mercury Exploration Project have revealed that chorus waves occur quite locally in the dawn sector of ...
