Electromagnetic Field in Dielectric Concentrator for Cherenkov Radiation*

Recently we have reported on axisymmetric dielectric concentrator for Cherenkov radiation that focuses almost the whole radiation in the vicinity of the given point (focus) located on the trajectory of the charge [1]. Particularly, we have shown that this structure can increase the field up to two orders of magnitude. In this report we continue investigation of this concentrating target and ana...

Observation of narrow-band terahertz coherent Cherenkov radiation from a cylindrical dielectric-lined waveguide.

We report experimental observation of narrow-band coherent Cherenkov radiation driven by a subpicosecond electron bunch traveling along the axis of a hollow cylindrical dielectric-lined waveguide. For an appropriate choice of dielectric wall thickness, a short-pulse beam current profile excites only the fundamental mode of the structure, producing energetic pulses in the terahertz range. We pre...

High power Cherenkov radiation from a relativistic particle rotating around a dielectric ball

Some characteristic features in the radiation from a relativistic electron uniformly rotating along an equatorial orbit around a dielectric ball have been studied. It was shown that at some harmonics, in case of weak absorption of radiation in the ball material, the electron may generate radiation field quanta exceeding in several dozens of times those generated by electron rotating in a contin...

Cherenkov Radiation in a Gravitational Wave Background

A covariant criterion for the emission of Cherenkov radiation 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. It is shown that vacuum interacting with curvature can give rise to Cherenkov radiation. The conically shaped spatial distribution of radiation is derived and its basic p...

Cherenkov radiation in a photon gas

It is well-known that a charged particle moving with constant velocity in vacuum does not radiate. In a medium the situation can be different. If the so called Cherenkov condition is satisfied, i.e. the particle velocity exceeds the phase speed in the medium, the particle will radiate. We show that a charge moving with a constant velocity in a gas of photons emits Cherenkov radiation, even in t...
