Обобщенная рефракционная диэлектрическая
модель влажных почв, учитывающая ионную релаксацию почвенной воды / В. Л. Миронов [и др.]> // Изв. вузов. Физика. - 2013. -
Т. 56
,
№ 3
. - С. 75-79
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.

Unidirectional Amplification and
Shaping of Optical Pulses by Three-Wave
Mixing
with Negative Phonons / A. K. Popov [и др.]> //
The 4th International Conference on Metamaterials, Photonic Crystals and Plasmonics (META’13) : Proceedings. - 2013. - P. 35-40. - Библиогр.: 30 назв.
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.

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.

The extraordinary properties of resonant four-wave
mixing
of backward and ordinary electromagnetic waves in doped negative-index materials are investigated. The feasibility of independent engineering of the negative refractive index and the nonlinear optical response as well as quantum control of the nonlinear propagation process in such composites is shown due to the coherent energy transfer from a control field to a signal field. Laser-induced transparency, quantum switching, frequency-tunable narrow-band filtering, amplification, and realizing a miniature mirrorless optical parametric generator of the entangled backward and ordinary waves are among the possible applications of the investigated processes.

Аннотация:
We present a study of the quantum properties of two light fields used in parametric four-wave
mixing
in a Raman-type atomic system. The system realizes an effective Hamiltonian of beam-splitter-type coupling between the light fields, which allows one 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:
It is shown that under resonant interaction conditions certain notions in nonlinear optics which are based on the Manley-Rowe relations no longer hold because of the interference of elementary quantum-mechanical processes. This conclusion is illustrated by numerical examples corresponding to the experiments performed. (C) 1999 American Institute of Physics. [S0021-3640(99)00512-5].

We investigate extraordinary features of optical parametric amplification of Stokes electromagnetic waves that originate from the three-wave

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.

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.

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:
Electron transmission in the two-, three-, and four-terminal nanostructures is considered under the influence of a radiation field. The frequency of the radiation field is tuned to the transition between the energy of a bound state and the Fermi energy of the incident electrons. The radiation induced resonant peaks and dips of the electron transport are exhibited for zero and low magnetic fields. It is shown that rotation of the radiation field polarization can effectively control the electron transport into different electrodes attached to the structures because of the symmetry of the structures. The resonant anomalies of the Hall resistance are found in a weak magnetic field. (C) 1998 American Institute of Physics. [S1063-7761(98)00412-0].

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.
