“…Potential applications of this selective cone formation lie in velocity-sensitive Cerenkov detectors and CL generation at selectable frequencies. Of potential use in particle detectors, it was recently shown that photonic crystals can slow down the propagation of CL appreciably and further control the behaviour of CL 88,89 . In both metamaterial and photonic crystal examples, CL can be modulated to disobey theories that were assumed fundamental to light generation.…”

The characteristic blue glow of Cerenkov luminescence (CL) arises from the interaction between a charged particle travelling faster than the phase velocity of light and a dielectric medium, such as water or tissue. As CL emanates from a variety of sources, such as cosmic events, particle accelerators, nuclear reactors and clinical radionuclides, it has been used in applications such as particle detection, dosimetry, and medical imaging and therapy. The combination of CL and nanoparticles for biomedicine has improved diagnosis and therapy, especially in oncological research. Although radioactive decay itself cannot be easily modulated, the associated CL can be through the use of nanoparticles, thus offering new applications in biomedical research. Advances in nanoparticles, metamaterials and photonic crystals have also yielded new behaviours of CL. Here, we review the physics behind Cerenkov luminescence and associated applications in biomedicine. We also show that by combining advances in nanotechnology and materials science with CL, new avenues for basic and applied sciences have opened.

“…Simple estimations can give the number of radiated quanta for an electron bunch passing through (or moving along the surface) of a photonic crystal [8,45]. Suppose the bunch duration is τ b = 10 −12 s (i.e., the length of about the radiation wavelength) and the number of electrons is n e = 10 9 [46,47].…”

“…Typically, in optical and microwave ranges, the perturbation theory does not apply to describe photon scattering by scatterers that form an electromagnetic (photonic) crystal as this theory does in the X-ray range. Nevertheless, as we have demonstrated earlier [12], using the scattering amplitude to describe the interaction of photons with a scattering center we can derive equations defining dynamical diffraction in electromagnetic crystals, and so we can use many of the results obtained in the PXR theory [12,20,21] to describe the emission of photons from relativistic particles moving in electromagnetic (photonic) crystals. This paper derives the expressions for spectral-angular distribution of quasi-Cherenkov radiation emitted by a relativistic particle traversing a photonic crystal.…”

The expressions for spectral-angular distribution of quasi-Cherenkov radiation emitted by a relativistic particle traversing a photonic crystal are derived. It is shown that for a relativistic particle, passing through a photonic crystal formed by periodically strained threads, the intensity of quasi-Cherenkov radiation emitted at small angles to the direction of particle motion, as contrasted to ordinary Cherenkov radiation, exhibits anisotropic properties as the the photon momentum is rotated about the direction of particle motion (as the crystal is rotated about the direction of particle motion at fixed-angle observation of the outcoming photon).The intensity of quasi-Cherenkov radiation in terahertz and optical ranges is shown to be high enough to allow the experimental study of quasi-Cherenkov radiation in these frequency ranges. *

“…For example, if the array spacing is of the order of millimeters, the resulting Cherenkov radiation wavelength is in the terahertz (THz) frequency range. Since this range was of significant interest during the past decade due to its prospective applications in various areas [19], corresponding wire structures can be used for the development of efficient THz radiation sources [20]. It should be noted that the usage of artificial crystals sufficiently changes the connection between the increment of instability and the beam density, resulting in a significant reduction in the beam current needed to reach the stimulated emission effect.…”

A theoretical approach for describing the electromagnetic radiation produced by a prolonged electron bunch propagating in the lattice of metallic wires of finite length is presented. This approach is based on the vibrator antenna theory and involves the approximate solving of Hallen's integral equation. For a single wire, it is also supposed that a wire is sufficiently thin and charge motion is relativistic. For many-wire structures, the approximation similar to the kinematic approach of the parametric x-ray radiation theory is additionally applied. The validity of the method is verified by numerical simulations with COMSOL Multiphysics. Possible applications of the interaction between charged particle bunches and artificial wire structures are discussed.
