On August 22, 1879, in a lecture to the British Association for the Advancement of Science, 1
Sir William Crookes announced that “radiant matter”(his term for the electrons emerging from …

Cherenkov radiation provides a valuable way to identify high-energy particles in a wide
momentum range, through the relation between the particle velocity and the Cherenkov …

Cherenkov radiation (CR), generated when charged particles move faster than the light
velocity in a medium, is an important radiation phenomenon of electron-matter interactions …

In conventional materials, Cherenkov radiation (CR) due to a moving charged particle is
associated with a broad frequency range and velocity threshold. Here, we show that using a …

We demonstrate that when a charged particle moves on top of a metal-slot metasurface
consisting of metallic slot resonators, strong Smith–Purcell electromagnetic (EM) radiation …

When a charged particle moves close and parallel to the surface of a Babinet metasurface
composed of metallic C-aperture resonators, strong electromagnetic radiation arises at …

ABSTRACT A conventional free-electron laser is useful but large, driven by a beam with
many relativistic electrons. Although, recently, keV electron beams have been used to excite …

The exploration of Terahertz (THz) waves has captivated researchers across diverse
scientific disciplines such as physics, spectroscopy, chemistry, biology, and engineering …

Vavilov–Cherenkov radiation (CR), an electromagnetic radiation emission that occurs when
a charged particle in a medium moves faster than the speed of light in the same medium …

We propose an orientation-dependent polarization manipulation by Cherenkov radiation
(CR) in a silicon-on-insulator (SOI) waveguide with a metasurface. By putting an electron …
