Fundamental limits of waves propagating in an inhomogeneous multilayer metal-dielectric mediumAllerton Press - Tập 19 - Trang 228-238 - 2011
B. A. Murmuzhev, R. N. Denisyuk
The dispersion equations have been derived for various types of orthogonally polarized waves in a five-layer dielectric medium shielded by metal screens. The dispersion characteristics of electromagnetically coupled waves propagating in two waveguide dielectric layers, isolated from each other and from the metal screens by separating and intermediate dielectric layers, have been investigated.

Formation of the Reactive Species of Oxygen, Nitrogen, and Carbon Dioxide in Aqueous Solutions under Physical ImpactsAllerton Press - Tập 28 - Trang 103-106 - 2020
V. I. Bruskov, A. V. Chernikov, V. E. Ivanov, E. E. Karmanova, S. V. Gudkov
A concept is proposed, according to which the water‒air system is an open nonequilibrium system capable of accumulating free energy; the latter can be released under certain weak resonance effects via standard high-energy processes. These processes break chemical bonds and cause formation of reactive species of oxygen, nitrogen, and carbon dioxide.
An enhanced refractive index with suppressed absorption in a graphene nanostructure under external magnetic fieldAllerton Press - Tập 25 - Trang 107-113 - 2017
H. R. Hamedi, A. Raheli, M. Sahrai
The dispersive-absorptive optical properties of a weak probe field are investigated based on quantum coherence and interference in a Landau-quantized graphene structure. It is found that an enhanced refractive index with vanishing absorption can be obtained in this structure through proper adjusting the controlling parameters of the system. The switching between superluminal and subluminal light p...... hiện toàn bộ
Laser Desorption of Organic Compound Ions from a Silicon Surface Modified by Laser IrradiationAllerton Press - Tập 28 - Trang 213-221 - 2020
A. V. Pento, S. M. Nikiforov, Ya. O. Simanovsky
Laser desorption of organic compound ions from specially prepared surfaces is known as surface-assisted laser desorption/ionization (SALDI). In this work the properties of a SALDI ion emitter obtained by two-stage laser treatment of crystalline silicon surface have been investigated. The laser surface treatment leads to the formation of a layer with nanoscale objects—quantum dots (QDs) less than 1...... hiện toàn bộ
Microwave pulse shortening in plasma relativistic high-current microwave electronicsAllerton Press - Tập 25 - Trang 130-136 - 2017
S. E. Ernyleva, O. T. Loza
We describe mechanisms of microwave pulse shortening in radiation sources with the power of about 108 W based on interaction between relativistic electron beams of nanosecond duration and preformed plasma. The shortening is mainly due to the electron return flow through the plasma, which leads to a multiple decrease in the linear gain of the microwave by the relativistic electron beam and in the r...... hiện toàn bộ

Non-markovian relaxation models in the theory of radiation of two-level atomsAllerton Press - Tập 19 - Trang 1-5 - 2011
V. V. Semin, A. V. Gorokhov
The short-memory processes in a system consisting of two dipole-dipole interacting atoms have been theoretically investigated. The radiation line profile is constructed, and the possibility of detecting memory effects in radiation spectra is discussed.
Heterostructures based on gapless graphene with different Fermi velocitiesAllerton Press - - 2017
A. K. Obukhova, P. L. Pekh, A. P. Silin
The properties of a single heterojunction between gapless graphenes with identical work functions but different Fermi velocities have been investigated. Reflection and transmission coefficients are obtained for charge carriers passing through this junction. It is shown that total internal reflection (with a critical angle the same as for light incident at an interface between two media) may occur ...... hiện toàn bộ
Localization of Rayleigh waves in microfluidic channels with quadratic profileAllerton Press - Tập 16 - Trang 300-304 - 2008
A. V. Zyryanova, V. G. Mozhaev
Localization of Rayleigh waves due to mechanical loading of the substrate surface by a liquid layer with quadratic thickness variation in the transverse direction was theoretically studied. Under conditions typical of acoustic biochips, strong localization of the wave field was revealed. This makes it possible to calculate the lowest waveguide modes of the microfluidic channel, neglecting its fini...... hiện toàn bộ
