Radiation of a charged particle moving parallel to an inhomogeneous surface is considered. Within a single formalism periodic and random gratings are examined. For the periodically inhomogeneous surface we derive new expressions for the dispersion re

We studied the structure of heterogenous DNA in the native state. There are two different regimes in the sample- to-sample fluctuations of the free energy in the native state, which can be interpreted via the concept of local free energy of base pair

We have theoretically shown that the yield of diffuse radiation generated by relativistic electrons passing random multilayered systems can be increased when a resonant condition is met. The resonant condition can be satisfied for the wavelength regi

A detailed theoretical and numerical analysis of the localization length in alternating metamaterial-birefringent random layered stacks, under uncorrelated thickness disorder, has been performed. Similar structures have recently been reported to supp
Light transport in a metal with two-dimensional hole arrays is considered. Analytical expression for a transmission coefficient in periodic, isolated and disordered cases are derived, assuming the existence of waveguide modes transverse tunneling in

We discuss radiation effects in systems with near zero dielectric constant. An enhancement of intensity by example of transition and diffusive radiations is demonstrated. A sharp peak in the transition radiation spectral-angular intensity is predicte

Based on the diffusional scattering of pseudophotons, we propose a new mechanism of x-ray radiation from a relativistic charged particle moving in a system consisting of microspheres distributed randomly in a dielectric material. The mechanism leads

A recent experiment was carried out to test a new type of X-ray detector. It consists of superconducting microspheres mixed randomly in dielectric material. X-ray radiation is generated from a relativistic charged particles passing through the detect

Intensity fluctuations under diffusion mechanism of radiation of charged particles are considered in this paper. The variances of integrated intensities are calculated. It is shown that they are small compared with the corresponding average quantitie

Radiation of a charged particle moving in a system of randomly spaced plates is considered. It is shown that the diffusion mechanism of radiation may play an important role. The total intensity of radiation is investigated and its quadratic dependenc
