Transition radiation is a fundamental process of light emission and occurs whenever a
charged particle moves across an inhomogeneous region. One feature of transition radiation …

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 detectors enable a valuable tool to identify high-energy particles. However, their
sensitivity and momentum coverage are limited by the refractive index of host materials …

Metamaterials (MTMs) are structured materials with subwavelength features that can be
engineered to have some unique properties not found in nature, such as negative refractive …

Cherenkov radiation (CR) is the characteristic blue glow that is generated during
radiotherapy or radioisotope decay. Its distribution and intensity naturally reflect the actual …

We present the observation and the detailed investigation of coherent Cherenkov diffraction
radiation (CChDR) in terms of spectral-angular characteristics. Electromagnetic simulations …

An all-metal metamaterial slow-wave structure (MSWS), which comprises a hollow circular
waveguide loaded by periodically arranged complementary electric split-ring resonators …

A miniaturized, high electronic efficiency, S-band metamaterial extended interaction klystron
(MEIK) is proposed. The metamaterial-based extended interaction resonant cavities were …

We present the first demonstration of high-power, reversed-Cherenkov wakefield radiation
by electron bunches passing through a metamaterial structure. The structure supports a …

Metamaterials are artificially constructed subwavelength structures exhibiting
unprecedented electromagnetic phenomena. In this letter, an S-band MW-level …
