In a conventional material, the coherent Cerenkov radiation due to a moving charged particle is associated with a velocity threshold, a forward-pointing radiation cone, and a forward direction of emission. We describe different behavior for the Cerenkov radiation in a photonic crystal. In particular, this radiation is intrinsically coupled with transition radiation and is observable without any threshold. Within one particle-velocity range, we found a radiation pattern with a backward-pointing…

A novel radiation emission from traveling charged particles in vacuum is theoretically demonstrated. This radiation is conical as in the Cherenkov radiation, but emerges in backward directions of the
Cherenkov Radiation from Photonic Bound States in the Continuum: Towards Compact Free-Electron Lasers
In conventional materials, Cherenkov radiation (CR) due to a moving charged particle is associated with a broad frequency range and velocity threshold. Here, we show that using a periodic grating
Cherenkov radiation in integrated nanophotonic structures
Vavilov–Cherenkov radiation (CR), an electromagnetic radiation emission that occurs when a charged particle in a medium moves faster than the speed of light in the same medium, plays an important

A modified two-dimensional Cherenkov radiation, which occurs on a high-index dielectric nano-film driven by uniformly moving electron-beam, which shows unique dispersion characteristics and may lead to promising applications in a broad range of fields.
Cherenkov Emission Generated by a Modulated Source in 2D Dispersive Photonic Crystal Slabs
This work presents a systematic numerical study of Cherenkov optical radiation generated by a modulated source that moves with uniform velocity on a two-dimensional (2D) photonic crystal (PCr) slab
Directing Cherenkov photons with spatial nonlocality
Abstract Cherenkov radiation in natural transparent materials is generally forward-propagating, owing to the positive group index of radiation modes. While negative-index metamaterials enable
Doppler radiation emitted by an oscillating dipole moving inside a photonic band-gap crystal.
It is demonstrated through numerical simulations that the radiation strength may be enhanced or inhibited according to the photonic band structure, and anomalous effects in the sign and magnitude of the Doppler shifts are possible, both outside and inside the gap.
Surface polariton Cherenkov light radiation source.
The results show that surface polariton Cherenkov light radiation source can generate radiation, from visible light to the ultraviolet frequency regime and the radiation power density can reach or even exceed 10(8) W/cm(2) depending on the beam energy and current density.
Flipping photons backward: reversed Cherenkov radiation
Charged particles moving faster than light in a medium produce Cherenkov radiation. In traditional, positive index-of-refraction materials this radiation travels forward. Metamaterials, with negative

Cherenkov radiation by a nonrelativistic electron bunch that moves above an interface of a vacuum-left-handed material has been investigated theoretically. The electron density of the bunch is


Cherenkov radiation at speeds below the light threshold: phonon-assisted phase matching.
The dipolar Cherenkov field, in the range of infrared-active phonons, is identical to that of phonon polaritons produced by impulsive laser excitation.
Smith-Purcell radiation from a charge running near the surface of a photonic crystal
Smith-Purcell radiation from a charge running near a photonic crystal is calculated for a slab system of a periodic array of dielectric spheres, with the photonic band effect taken into account
Slow group velocity and Cherenkov radiation.
The aperture of the group cone on which the intensity of the radiation peaks is much smaller than that of the usual wave cone associated with the Cherenkov coherence condition in a coherently driven medium.
Theory of light propagation in strongly modulated photonic crystals: Refractionlike behavior in the vicinity of the photonic band gap
Although light propagation in weakly modulated photonic crystals is basically similar to propagation in a diffraction grating in which conventional refractive index loses its meaning, we demonstrate

A scattering theoretical approach is used to describe the generation of both transition and Cerenkov radiation due to the passage of fast electrons through layered, in general absorptive,
Inhibited spontaneous emission in solid-state physics and electronics.
If a three-dimensionally periodic dielectric structure has an electromagnetic band gap which overlaps the electronic band edge, then spontaneous emission can be rigorously forbidden.
Cerenkov radiation and its applications
The paper opens with a brief review of the original discovery of the radiation and the physical principles of the process that gives rise to it. This is followed by an elementary account of the

Abstract We analyze how the frequency dependence of the electric permittivity e affects the electromagnetic field radiated by a point charge uniformly moving in a medium. It turns out that a moving
