real permittivity -- water content -- mineral soil -- soil moisture -- crossover frequency
Аннотация: In this research, it was studied the crossover frequencies of the spectra of the real part of the permittivity of moist mineral soils with different clay content from 10 to 64% in the frequency range from 15 MHz to 15 GHz and in the temperature range from 25 to 0 °C. Based on the experimental dependences obtained, empirical models were proposed for the average crossover frequency of the soil of the real part of the permittivity spectra in the range of changes of these frequencies values with temperature changes, as well as for the half-widths of the ranges of changes.

Аннотация: A correlation between the temperatures corresponding to the maxima of the sound attenuation and temperature resistance coefficient in the RexMn1-xS solid solutions related to the condensation of electrons and holes has been established. X-ray diffraction, energy-dispersive X-ray spectrum, and scanning electron microscope techniques have been used to investigate the microstructure of the samples. In the Yb0.2Mn0.8S compound, a decrease in the ultrasound attenuation with increasing temperature has been observed. The functional dependences of the electrosound on the ultrasound intensity and carrier type and the change in the electrosound sign with temperature have been established. The asymmetry of the I-V characteristic depending on the ultrasound intensity and the attenuation coefficient depending on the electric field has been found. The nonlinear attenuation of the ultrasound as a function of the intensity has been observed. Model of elastic and inelastic scattering of current carriers by acoustic phonons, deformation interaction is used to explain the asymmetry.

    Методика синтеза одномерно сканирующих антенн на основе модулированных метаповерхностей / К. В. Лемберг, Д. А. Шабанов, Е. О. Грушевский, И. В. Подшивалов // Журн. СФУ.

Аннотация: В работе описана методика синтеза сканирующих в одной плоскости апертурных антенн вытекающей волны, построенных на основе метаповерхностей с модулированным поверхностным импедансом. Такие антенны состоят из цепочки субволновых резонансных элементарных ячеек, имеющих две степени свободы, одна из которых используется для модуляции импеданса метаповерхности, а вторая для динамического изменения направления излучения вытекающей волны. В качестве примера применения методики была синтезирована антенна на основе металлической гофрированной структуры, позволяющая проводить сканирование в диапазоне углов от 4° до 42° на частоте 27 ГГц и имеющая КНД от 26.4 до 30.1 дБи. Антенны представленного типа позволяют реализовывать одномерное электронное сканирование существенно более простым способом, чем фазированные антенные решетки,
This paper describes a method for the synthesis of one-dimensional scanning leaky-wave antennas based on metasurfaces with modulated surface impedance. Such antennas consist of a chain of subwavelength resonant elementary cells with two degrees of freedom, one of which is used to modulate the impedance of the metasurface and the other to dynamically change the radiation direction of the leaky wave. As an example of the proposed method application antenna based on a metallic corrugated structure was synthesized, which allows scanning in the range from 4° to 42° at 27 GHz and has a directivity from 26.4 to 30.1 dBi. Antennas of the described type allow to realize one-dimensional electronic scanning in a much simpler way than phased array antennas.

Аннотация: We have explored the dynamic response of in-plane magnetized thin permalloy films excited by microwave fields of high amplitudes (up to 3 Oe) at 1 GHz. The response was detected using a microstrip line by measuring the second harmonic signal generated by the dynamic components of the uniform magnetization. The data measured at ferromagnetic resonance showed the threshold effect of the Suhl parametric instability process. With the increase of the microwave power above the threshold value, the dynamic response revealed an intricate nonlinear behavior, including the emergence of an additional threshold. This second threshold can be explained in terms of the "stage by stage"process of parametric spin wave excitation following the S theory of Zakharov, L'vov, and Starobinets.

Аннотация: We have established numerically the physical pattern and conditions for formation of nanosized bubbles in aqueous medium around biocompatible plasmonic nanoparticles (NPs) selectively bound to the membrane of the malignant cells by means of DNA-aptamers under the action of picosecond laser radiation. The results obtained are based on the finite volume method and hydrodynamic models underlying the ANSYS Fluent package with extended capabilities. We have found the main features and previously unknown dominant factors of the damage effect on the cell membrane at the moment of the bubble nucleation around the plasmonic NPs of different types taking into account the influence of the closely located membrane. Information on the kinetics of spatial distribution of pressure, temperature and the relative proportion of vapor in the 'nanoparticle-membrane-medium' system have been obtained. The attention is drawn to the advantages of using biocompatible, perfectly absorbing core–shell plasmonic NPs for anti-tumor therapy characterized by an increased mechanical effect on malignant cell membranes at lower laser radiation intensity and the spectral position of their plasmon resonance (λ = 700 nm) in the hemoglobin transparency range. This ensures penetration of laser radiation deep into tissues. The paper is provided with an extensive review of key publications and the state-of-art in this area.

Dispersion (waves) -- Electric fields -- Metal ions -- Neutron scattering -- Perovskite -- Rare earths -- Spin dynamics -- Temperature -- Terbium compounds
Аннотация: The low-temperature spin dynamics of the orthorhombic TbFeO3 perovskite has been studied. It has been found that the inelastic neutron scattering (INS) spectrum of the investigated compound contains two modes corresponding to different sublattices. It is shown that the iron subsystem orders antiferromagnetically at TN=632 K and exhibits the high-energy magnon dispersion. The magnetic dynamics of this subsystem has been described within the linear spin wave theory and the in-plane and out-of-plane exchange anisotropy has been demonstrated. The approach proposed previously to describe the magnon dispersion in the TmFeO3 compound has been used. Three levels of the nondispersive crystal electric field corresponding to Tb3+ ions have been found in the energy region below 40 meV at about 17, 26, and 35 meV. The behavior of the magnetic correlation length of the terbium subsystem has been determined by studying the diffuse scattering at different temperatures. The evolution of this subsystem has been numerically described within the point charge model. It is shown that the numerical data agree satisfactorily with the experiment and with the general concept of the single-ion approximation applied to the rare-earth subsystem of orthorhombic perovskites.

They characterized by a simple design, but a relatively complex synthesis procedure. The paper briefly describes the modulated metasurface antennas principle of operation, and gives a specific method for calculating the anisotropic cell impedance tensor based on the calculation of cell eigenmodes in the infinite surface approximation. The method is intended for use at the first stage of the metasurface antenna synthesis, which consists in creating a database of cell tensorial impedances.
