A beam of electrons crossed just a few millimeters of plasma, then helped trigger an effect that usually belongs to massive ...

(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 ...

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 ...

(Aitor Diago/Moment/Getty Images) For the first time, physicists have observed that 'holes' in light can move faster than the ...

Free-electron lasers can be tuned to operate over a wide range of wavelengths, but they conventionally require large-scale ...

Electron holography is based on the fundamental principles of holography, which involves the recording and reconstruction of wavefronts. In holography, a hologram is created by capturing 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 ...

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 ...

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

(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 ...
