N.; Grushevskaya, H. V.; Krylova, N. G.; Lipnevich, I. V.; Orekhovskaya, T. I. Аннотация: Raman scattering in dielectric nanostructures on the base of aluminum oxide was studied. A method of high dielectric nanocomposite fabrication was proposed. Metalcontaining conducting Langmuir – Blodgett films were shown to shield the anodic nanoporous alumina from the action of strong electrical fields.

Аннотация: Plasma is a basic example of the tunneling effect in electrodynamics, however, to date there are no systematic studies of electromagnetic radiation tunneling in plasma. Discussion of various approaches to studying this issue leads to the need for a thorough solution of the non-stationary problem of electromagnetic pulse propagation in plasma /1/. In this paper, the propagation of electromagnetic pulse is numerically investigated by the finite-difference time-domain (FDTD) method /2/ for solving Maxwell's equations, using an open-source software package /3/. The dispersive character of medium is treated via using an additional equation for polarization.

Temperature Effect Авторы: Rozenbaum, V. M.; Shapochkina, I. V.; Trakhtenberg, L. I. Аннотация: A pulsating ratchet with a spatially periodic double-well potential profile undergoing shift fluctuations for half a period is considered. The motion direction in such a ratchet is determined by the probability of overcoming which of the barriers surrounding the shallow potential well is greater. At relatively high temperatures, in accordance with the Arrhenius law, the probabilities of overcoming the barriers are determined by their heights, and at temperatures close to absolute zero, when the ratchet moves according to the tunnel mechanism, the barrier shapes are also important. Therefore, for narrow high and low wide barriers, the overcoming mechanism may turn out to be different and, moreover, dependent on temperature. As a result, a temperature-induced change in the direction of the ratchet motion is possible. A simple interpolation theory is presented to illustrate this effect. Simple criteria are formulated for the shape of the potential relief, using which one can experimentally observe motion reversal.
