Аннотация: The effect of the residual catalyst for the synthesis of multi-walled carbon nanotubes (MWCNTs) on the electrophysical properties of MWCNT-polyethylene composites produced by melt mechanical mixing was studied. The residual catalyst content was varied by changing the MWCNTs synthesis time. The nanotubes used in the work were characterized using transmission and scanning electron microscopy, atomic emission analysis, X-ray phase analysis, and magnetic permeability measurements. The structure of the synthesized composites was studied using optical and scanning electron microscopy. The dependences of the specific magnetization on the applied magnetic field, bulk electrical conductivity on the volumetric content of the filler in the composite, and the frequency dependences of the reflection, transmission, and absorption of electromagnetic radiation in the range 0.01-18 GHz were obtained. It was established that the obtained composites are characterized by a uniform distribution of nanotubes in the polymer matrix, and the dependence of the bulk electrical conductivity on the content of MWCNTs in the composite has a percolation character. Variation in the synthesis time of nanotubes allows producing MWCNTs with a high content of ferromagnetic particles, which are an alloy close in stoichiometry to the composition of the active component of the catalyst. It was shown that the use of composites modified with MWCNTs with a high content of residual catalyst is more effective for absorbing electromagnetic radiation due to an increase in their magnetic losses.

Аннотация: We present a study of the quantum properties of two light fields used to parametric four-wave mixing in a Raman type atomic system. The system realizes an effective Hamiltonian of beamsplitter type coupling between the light fields, which allows to control squeezing and amplitude distribution of the light fields, as well as realizing their entanglement. The scheme can be feasibly applied to engineer the quantum properties of two single-mode light fields in properly chosen input states.

Аннотация: Three-wave mixing of ordinary electromagnetic waves and the waves with contra-directed phase and group velocities in the pulsed regimes is shown to be accompanied by unusual transient processes. We have investigated how attenuation and phase mismatch of the coupled waves in the metamaterials change the properties of parametric amplification and the threshold intensity of the pump wave which is of critical importance.

Аннотация: We propose metamaterial (MM) that supports a mixture of three or more normal and backward electromagnetic modes with equal co-directed phase velocities and mutually contra-directed energy fluxes. This enables extraordinary three-wave mixing, greatly enhanced optical parametric amplification, and frequency-changing generation of entangled photons in the reflection direction. Proof-of-principle numerical simulation of such processes is presented based on the particular example of the wave-guided terahertz waves contra-propagating in the MM made of carbon nanotubes.

Аннотация: Three-wave mixing of ordinary and backward electromagnetic waves in a pulsed regime is investigated in the metamaterials that enable the coexistence and phase-matching of such waves. It is shown that the opposite direction of phase velocity and energy flux in backward waves gives rise to extraordinary transient processes due to greatly enhanced optical parametric amplification and frequency up- and down-shifting nonlinear reflectivity. The differences are illustrated through comparison with the counterparts in ordinary, co-propagating settings. © 2016 Optical Society of America.

Аннотация: A mono-frequency dielectric model for the agricultural soil both thawed and frozen has been developed. The model is based on the soil dielectric measurements carried out in the ranges of volumetric moisture from 0,03 to 0,51 cm3/ cm3, dry soil density from 1.12 to 1.64 g/cm3, and temperature from -30 to 25°C (heating run), at the frequency of 1.4 GHz used in the SMOS mission. To fit the results of measurements of the soil complex refractive index (CRI) as a function of soil moisture, the refractive mixing model was applied. As a result, the parameters of the refractive mixing model linked to soil solids, as well as the bound, transient, and free soil water components were derived as a function of temperature. The error of the proposed dielectric model was shown to be in the order of the dielectric measurement error itself. © 2015 IEEE.

Mimicking Frequency-mixing in Nonlinear Optical Negative-index Metamaterials: nidirectional Raman Amplification and Shaping of Optical Pulses / A. K. Popov [et al.] // 16th International Conference Laser Optics (LO 2014) : Proceedings : IEEE Computer Society, 2014. - Ст. WeR8-25 . - ISBN 978-1-4799-3884-1
Аннотация: The possibility of mimicking of huge enhancement of coherent nonlinear optical frequency-mixing processes, is investigated in Raman crystals. Negative dispersion of optical phonons plays a key role for such an analogy. A possibility to greatly enhance frequency conversion efficiency of stimulated Raman scattering is shown by making use of extraordinary properties of three-wave mixing of ordinary optical and backward elastic waves. Specific properties of the indicated nonlinear optical process in short- pulse regime are investigated and the possibility to eliminate such a fundamental detrimental effect as fast damping of optical phonons on the process concerned is shown.

Generalized refractive mixing dielectric model of moist soils considering ionic relaxation of soil water / V. L. Mironov [et al.] // Rus. Phys. J. - 2013. - Vol. 56, Is. 3. - P. 319-324DOI 10.1007/s11182-013-0034-4
Аннотация: A generalized multi-relaxation refractive mixing dielectric model of moist soils is suggested for frequencies in the range from 0.2 to 14.8 GHz. The model is based on dielectric measurements in this frequency range at a temperature of 20A degrees D for relative moisture content (by weight) changing from 2 to 43%. The model expands the range of applicability of the single-relaxation model suggested previously to the megahertz frequency range with allowance for the Maxwell-Wagner ionic relaxation which is clearly manifested in this frequency range for bound soil water. It is demonstrated that the error in calculating the complex dielectric permittivity spectra of the moist soil has the same order of magnitude as the error of experimental data used for model construction.

Аннотация: In this letter, a multirelaxation generalized refractive mixing dielectric model (GRMDM) for moist soil is proposed and substantiated in the frequency range from 0.04 to 26.5 GHz. This model is based on the methodology of a single-relaxation GRMDM which accounts only for the dipole relaxation of water molecules in the gigahertz frequency range. The proposed multirelaxation GRMDM takes into account both the dipole (Debye) and ionic (Maxwell-Wagner) relaxations of soil water molecules. For this purpose, it uses a two-frequency Debye relaxation equation for the dielectric spectra of bound water. The spectroscopic parameters of the multirelaxation GRMDM were derived by fitting the spectra calculated by this model to the respective measured ones. The main advantage of this model is that it predicts the complex dielectric constant of moist soils throughout the megahertz and gigahertz frequency ranges with the same error as the single-relaxation GRMDM does only in the gigahertz range.

Аннотация: Предложена многорелаксационная обобщенная рефракционная диэлектрическая модель влажных почв в диапазоне частот от 0, 2 до 14, 8 ГГц. Модель основана на данных диэлектрических измерений, проведенных в этом частотном диапазоне, при температуре 20 °С, для относительных весовых влажностей, изменяющихся в пределах от 2 до 43 %. Созданная модель расширяет частотный диапазон применимости ранее предложенной однорелаксационной модели в область мегагерцового диапазона за счет учета ионной релаксации Максвелла -Вагнера, которая существенно проявляется в связанной почвенной воде в этом диапазоне частот. Показано, что ошибка расчета с помощью предложенной модели спектров комплексной диэлектрической проницаемости влажной почвы имеет тот же порядок, что и погрешность экспериментальных данных, используемых при построении модели.

Аннотация: A possibility to greatly enhance frequency-conversion efficiency of stimulated Raman scattering is shown by making use of extraordinary properties of three-wave mixing of ordinary and backward waves. Such processes are commonly attributed to negative-index plasmonic metamaterials. This work demonstrates the possibility to replace such metamaterials that are very challenging to engineer by readily available crystals which support elastic waves with contra-directed phase and group velocities. The main goal of this work was to investigate specific properties of indicated nonlinear optical process in short-pulse regime and to show that it enables elimination of fundamental detrimental effect of fast damping of optical phonons on the process concerned. Among the applications is the possibility of creation of a family of unique photonic devices such as unidirectional Raman amplifiers and femtosecond pulse shapers with greatly improved operational properties.

Аннотация: A possibility to greatly enhance frequency-conversion efficiency of stimulated Raman scattering is shown by making use of extraordinary properties of three-wave mixing of ordinary and backward waves. Such processes are commonly attributed to negative-index plasmonic metamaterials. This work demonstrates the possibility to replace such metamaterials that are very challenging to engineer by readily available crystals which support elastic waves with contradirected phase and group velocities. The main goal of this work is to investigate specific properties of indicated nonlinear optical process in short pulse regime and to show that it enables elimination of fundamental detrimental effect of fast damping of optical phonons on the process concerned. Among the applications is the possibility of creation of a family of unique photonic devices such as unidirectional Raman amplifiers and femtosecond pulse shapers with greatly improved operational properties.

Multi-relaxation generalized refractive mixing dielectric model of moist soils / V. L. Mironov, P. P. Bobrov, S. V. Fomin // IEEE International Geoscience and Remote Sensing Symposium (IGRASS) : Proceedings. - Munich, 2012. - P. 5177-5179, DOI 10.1109/IGARSS.2012.6350887 . - ISBN 978-1-4673-1159-5
Аннотация: In this paper, a multi-relaxation generalized refractive mixing dielectric model (GRMDM) for moist soil is proposed and substantiated in the frequency range from 0.03 to 26.5 GHz. This model is based on the GRMDM of [1] developed in the range of GHz frequencies, considering only the dipole relaxation of water in the soil. The error of this model was shown to noticeably increase with the transition to the MHz range. Because in this range, one more relaxation, that is, ionic (Maxwell-Wagner) relaxation largely affects on the complex dielectric constant. The multi-frequency relaxation GRMDM developed in this paper compensates for this disadvantage of the single-relaxation GRMDM. In this model, the two-frequency relaxation Debye equation for the dielectric spectra of bound water has been used, thus expanding the scope of the GRMDM to the MHz range. The main advantage of this model is that it predicts complex dielectric constant of moist soils simultaneously in the GHz and MHz ranges.

Аннотация: We investigate extraordinary features of optical parametric amplification of Stokes electromagnetic waves that originate from the three-wave mixing of a backward phonon wave with negative group velocity and two ordinary electromagnetic waves. Such properties were earlier shown to exist only in plasmonic negative-index metamaterials that are very challenging to fabricate. Nonlinear optical photonic devices with properties similar to those predicted for negative-index metamaterials are proposed. (C) 2011 Optical Society of America
