Transforming Cherenkov radiation in metamaterials [PDF]
SPIE Proceedings, 2015 In this contribution, we explore the generation of light in transformation-optical media. When charged particles move through a transformation-optical material with a speed larger than the phase velocity of light in the medium, Cherenkov light is emitted.

Characteristics of Cherenkov Radiation in Naturally Occuring Ice
, 2016 We revisit the theory of Cherenkov radiation in uniaxial crystals. Historically, a number of flawed attempts have been made at explaining this radiation phenomenon and a consistent error-free description is nowhere available.

The role of energy-momentum conservation in emission of Cherenkov gluons [PDF]
, 2007 The famous formula for the emission angle of Cherenkov radiation should be modified when applied to hadronic reactions because of recoil effects. They impose the upper limit on the energy of the gluon emitted at a given angle. Also, it leads to essential

Radiation spectrum of an electron moving in a spiralin medium
Condensed Matter Physics, 2007 The action of the Doppler effect on the particularities of radiation power spectral distribution of an electron moving in a spiral in a medium has been investigated near the Cherenkov threshold.

Bogoliubov-Cherenkov radiation in an atom laser [PDF]
Physical Review A, 2018 We develop a simple yet powerful technique to study Bogoliubov-Cherenkov radiation by producing a pulsed atom laser from a strongly confined Bose-Einstein condensate. Such radiation results when the atom laser pulse falls past a Bose-Einstein condensate at high-hypersonic speeds, modifying the spatial profile to display a characteristic twin jet ...

Spectral and amplitude-time characteristics of crystals excited by a runaway electron beam
Matter and Radiation at Extremes, 2019 The generation of runaway electrons (REs) is a significant problem in tokamak installations, causing energy loss, and melting and vaporization of the walls of the vacuum chamber.

Radiation Spectrum of Sequence of Electrons Moving in Spiral in Medium
Фізика і хімія твердого тіла, 2019 Integral expressions for spectral-angular and spectral distributions of the radiation power for the sequence of electrons moving in magnetic fields in isotropic transparent medium are investigated using the improved Lorentz`s self-interaction method ...
