Observation of 2D Cherenkov Radiation

Physical Review X, 2023
For over 80 years of research, the conventional description of free-electron radiation phenomena, such as Cherenkov radiation, has remained unchanged: classical three-dimensional electromagnetic waves.

Accelerated-Cherenkov radiation and signatures of radiation reaction [PDF]

New Journal of Physics, 2019
In this manuscript we examine an accelerated charged particle moving through an optical medium, and explore the emission of accelerated-Cherenkov radiation.

Broadband and Tunable 920-nm Femtosecond Pulse Generated by an All-Fiber Er:Fiber Laser System

IEEE Access, 2021
Fiber-optic Cherenkov radiation (FOCR) is a promising nonlinear process that is widely used for nonlinear wavelength conversion. In this study, an all-fiber 920-nm femtosecond pulse source is experimentally demonstrated by using Cherenkov radiation.

Spatial distribution of Cherenkov radiation in periodic dielectric media

, 2009
The nontrivial dispersion relation of a periodic medium affects both the spectral and the spatial distribution of Cherenkov radiation. We present a theory of the spatial distribution of Cherenkov radiation in the far-field zone inside arbitrary three ...

Vacuum Cherenkov radiation

, 2004
Within the classical Maxwell-Chern-Simons limit of the Standard-Model Extension (SME), the emission of light by uniformly moving charges is studied confirming the possibility of a Cherenkov-type effect.

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.

Constraint on ghost-free bigravity from gravitational Cherenkov radiation [PDF]

, 2016
We investigate gravitational Cherenkov radiation in a healthy branch of background solutions in the ghost-free bigravity model. In this model, because of the modification of dispersion relations, each polarization mode can possess subluminal phase ...

Fine structure of Vavilov-Cherenkov radiation near the Cherenkov threshold

, 1999
We analyze the Vavilov-Cherenkov radiation (VCR) in a dispersive nontransparent dielectric air-like medium both below and above the Cherenkov threshold, in the framework of classical electrodynamics.

Signal Characteristics from Electromagnetic Cascades in Ice [PDF]

, 2001
We investigate the development of electromagnetic cascades in ice using a GEANT Monte Carlo simulation. We examine the Cherenkov pulse that is generated by the charge excess that develops and propagates with the shower.

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 ...
