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) Imagine standing by a lake and throwing a stone into the water. Waves spread out in circular patterns and can reflect at obstacles and boundaries. Researchers at the University of ...

Physicists have detected laser-assisted electron scattering using circularly polarized light for the first time, revealing ...

In a breakthrough discovery, scientists have unveiled a novel method for X-ray generation, offering enhanced flexibility in emitting X-rays in various directions or focusing them. A nurse checks the ...

However, the most important point is the need to limit the influence of diffraction contrast to obtain accurate measurements. In this respect, the use of a plane electron wave for EH is clearly ...

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 ...

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...

Scientists at the University of Konstanz in Germany have advanced ultrafast electron microscopy to unprecedented time resolution. Reporting in Science Advances, the research team presents a method for ...

(b) The electrons are waveshaped using a waveshaping instrument, such as a phase plate, and they form regular wave patterns (green rings) that overlap with the positions of the graphene’s atoms (red ...

Researchers from Tokyo Metropolitan University have succeeded in detecting laser-assisted electron scattering (LAES) using ...
