Observation of the reversed Cherenkov radiation [PDF]

Nature Communications, 2017
Reversed Cherenkov radiation has not been observed due to the absence of suitable all-metal left-handed materials for beam transport and suitable couplers for extracting the signal. Here, Duanet al.

On-chip Cherenkov radiation tuning in 3.2-14 THz [PDF]

Nature Communications
Cherenkov radiation has attracted much attention for promoting the free electron radiation sources. Using hyperbolic metamaterial, Cherenkov radiation can be excited using low-energy electrons and thus on-chip free electron radiation source has been ...

Slow group velocity and Cherenkov radiation [PDF]

Physical Review Letters, 2001
We theoretically study the effect of ultraslow group velocities on the emission of Vavilov-Cherenkov radiation in a coherently driven medium. We show that in this case the aperture of the group cone on which the intensity of the radiation peaks is much ...

Imaging radiation dose in breast radiotherapy by X-ray CT calibration of Cherenkov light [PDF]

Nature Communications, 2020
Imaging Cherenkov emission during radiotherapy can provide information on the delivered radiation dose, but is attenuated by optical properties of the tissue.

Cherenkov Gravitational Radiation during the Radiation Era [PDF]

Universe, 2021
Cherenkov radiation may occur whenever the source is moving faster than the waves it generates. In a radiation dominated universe, with equation-of-state w=1/3, we have recently shown that the Bardeen scalar-metric perturbations contribute to the ...

Dispersive 2D Cherenkov radiation on a dielectric nano-film [PDF]

Scientific Reports, 2017
We report a modified two-dimensional Cherenkov radiation, which occurs on a high-index dielectric nano-film driven by uniformly moving electron-beam. It is essentially different from the ordinary Cherenkov radiation in that, in the nondispersive medium ...

Backward Cherenkov radiation emitted by polariton solitons in a microcavity wire [PDF]

Nature Communications, 2017
Cherenkov radiation is generated from fast electrons and its optical analogue plays an important role in many nonlinear optical effects. Here, Skryabin et al.

Cherenkov radiation in a gravitational wave background [PDF]

Classical and Quantum Gravity, 2000
A covariant criterion for the Cherenkov radiation emission in the field of a non-linear gravitational wave is considered in the framework of exact integrable models of particle dynamics and electromagnetic wave propagation.
