    Analysis of the quality factor of the optical half-wavelength resonator / B. A. Belyaev, V. V. Tyurnev // Microwave Opt. Techn. Lett. - 2013. - Vol. 55, Is. 7. - P. 1613-1616DOI 10.1002/mop.27662
   Перевод заглавия: Анализ добротности оптического полуволнового резонатора
Аннотация: An electrodynamic analysis of an optical resonator comprising a half-wavelength dielectric layer that is covered from both sides by quarter-wavelength layers with higher and lower refractive indices (RIs) is carried out.For such a resonator, the dependences of the external quality factor on number and RIs of the layers are obtained first. That allows one to determine minimum number of the layers in the structure to achieve the required quality factor at practically any contrast of the RIs. The results of this study provide an easy way to optimize the structures of 1D photonic crystal devices, particularly high-selectivity bandpass filters.

Bandpass filter with an ultra wide stopband designed on miniaturized coaxial resonators / B. A. Belyaev [et al.] // J. Commun. Technol. Electron. - 2013. - Vol. 58, No. 2. - P. 110-117DOI 10.1134/S1064226913020022
Аннотация: Characteristics of a new miniaturized coaxial resonator are theoretically investigated. It is shown that the first resonant frequency of the resonator can be significantly lowered relative to the second one and the resonator dimensions can be considerably decreased as compared to those of a traditional dielectric filled quarter wavelength coaxial resonator. Based on the investigated resonator, a fourth order bandpass filter has been designed and fabricated. The filter stopband at a level of no worse than –90 dB extends to the frequency that exceeds the passband center frequency by a factor of 47. Calculated frequency responses are in good agreement with those measured on the fabricated filter prototypes.

    Nonlinear backward-wave photonic metamaterials / A. K. Popov [et al.] // Adv. Sci.Technol. - 2013. - Vol. 77. - P. 246-252DOI 10.4028/www.scientific.net/AST.77.246
   Перевод заглавия: Нелинейные метаматериалы с обратной волной для фотоники
Аннотация: Novel concepts of nonlinear-optical (NLO) photonic metamaterial are proposed. They concern photonic materials that support backward electromagnetic or vibration waves (BWs) and provide coherent nonlinear-optical energy exchange between ordinary and BWs as applied to three- and four-wave mixing processes. Three different classes of materials which support BWs are considered: plasmonic negative-index (NI) metamaterials (NIMs), metamaterials with specially engineered spatial dispersion of the nanoscopic building blocks, such as standing carbon nanotubes, and crystals that support optical phonons with negative group velocity. The possibility to exploit ordinary crystals instead of plasmonic NLO metamaterials that are very challenging to engineer is proposed. It is shown that extraordinary nonlinear optical frequency-conversion propagation processes attributed to NIMs can be mimicked in the proposed metamaterials. It is also shown that the detrimental effects of strong losses can be mitigated in the short-pulse regimes, which exhibit exotic properties when ordinary and BWs are involved in the NLO coupling. Comparative review of unparallel properties of coherent energy exchange between ordinary and backward electromagnetic waves in NIMs and between ordinary electromagnetic waves coupled through backward vibration waves is given. Unique photonic devices are proposed.

    A dual-mode split microstrip resonator and Its applications in frequency selective devices / B. A. Belyaev, A. M. Serzhantov, V. V. Tyurnev // Microwave Opt. Technol. Lett. - 2013. - Vol. 55, Is. 9. - P. 2186–2190DOI 10.1002/mop.27806
   Перевод заглавия: Двухмодовой расщепленный микрополосковый резонатор и его применения в частотно-селективных устройствах
Аннотация: A dual-mode microstrip resonator whose strip conductor is partially split from its one end by a longitudinal slot has been studied. The resonator has two fundamental modes, even and odd ones. The difference of their frequencies is controlled by varying the slot length. Based on such resonators, original structures of a diplexer and passband filters including dual-band have been designed. Measured performances of their fabricated prototypes prove applicability of designed devices in microwave engineering.

Аннотация: A novel miniature stripline resonator performed on a double-layer suspended substrate and bandpass filters (BPFs) based on it are proposed. The filters have wide stopband with high attenuation. A fifth-order BPF has been designed and fabricated. The filter stopband at level of −100 dB extends up to the frequency that exceeds the passband center frequency by factor of 10. It is shown that miniature filters based on the proposed resonator could be effectively fabricated by low temperature cofired ceramics technology.

Аннотация: A comparative multitechnique study (including transmission electron microscopy, synchrotron radiation, static magnetisation, magnetic circular dichroism and electron magnetic resonance) has been carried out of nanoparticle-containing borate glasses of two different types: (i) with iron and manganese oxide additives and (ii) with iron and rare earth oxide additives. Due to the presence of magnetic nanoparticles, these glasses have a nonlinear magnetic field dependence of magnetization with hysteresis and saturation while remaining transparent in the visible and near-infrared spectral ranges. The nature of the nanoparticles has been identified as manganese ferrite for type (i) glasses and maghemite for type (ii) glasses. The synchrotron radiation studies as well as the computer-assisted electron magnetic resonance provide an insight into the morphological characteristics of the magnetic nanoparticles in the glass.

Autotrophic synthesis -- Cupriavidus eutrophus -- Polyhydroxyalkanoates
Аннотация: Synthesis of polyhydroxyalkanoates (PHAs) by a new strain of Cupriavidus - Cupriavidus eutrophus B-10646 - was investigated under autotrophic growth conditions. Under chemostat, at the specific flow rate D=0.1h-1, on sole carbon substrate (CO2), with nitrogen, sulfur, phosphorus, potassium, and manganese used as growth limiting elements, the highest poly(3-hydroxybutyrate) [P(3HB)] yields were obtained under nitrogen deficiency. In batch autotrophic culture, in the fermenter with oxygen mass transfer coefficient 0.460h-1, P(3HB) yields reached 85% of dry cell weight (DCW) and DCW reached 50g/l. Concentrations of supplementary PHA precursor substrates (valerate, hexanoate, ?-butyrolactone) and culture conditions were varied to produce, for the first time under autotrophic growth conditions, PHA ter- and tetra-polymers with widely varying major fractions of 3-hydroxybutyrate, 4-hydroxybutyrate, 3-hydroxyvalerate, and 3-hydroxyhexanoate monomer units. Investigation of the high-purity PHA specimens showed significant differences in their physicochemical and physicomechanical properties. В© 2013 Elsevier Ltd.

Аннотация: Описывается оригинальная технология покрытия графитовыми слоями внутренних стенок пор в пластине анодного оксида алюминия. Для синтеза графитизированного углерода при низких температурах (от 500 °С) использован процесс осаждения из газовой фазы с применением оригинального катализатора, предварительно внедренного в поры. Исследована морфология полученных структур, а также показано, что графит, осажденный на стенки пор оксида алюминия, формирует цилиндирическую трубку - нанотубулен. Обсуждаются возможности использования полученных структур в качестве функционально активных элементов различного назначения, например, наномембран с управляемыми транспортными свойствами, элементов наноэлектроники и др.
The paper describes the original coating technology of covering the inner walls of the pores with the graphite layers in the anodic aluminum oxide plate. For the synthesis of graphitizing carbon at low temperatures (500 °C) the deposition process from the gas phase was used, with the use of the original catalyst pre-embedded in the pores. The morphology of the resulting structures is investigated and it is shown that the carbon deposited on the pore walls of the alumina forms the cylindrical tube - nanotubulene. The possibility of use of the resulting structures as functionally active elements for various purposes, such as nanomembranes with controlled transport properties, and other elements of nanoelectronics, is discussed.

Аннотация: This study is concerned with the optical response of an electro-optical material consisting of nematic liquid crystal as well as ionic surfactant as a dopant. The dopant is a key component to carry out the working of the resulting device through configuration switching. The operational principle is based on the surface anchoring transition induced by a steady electric field. The dynamic characteristics of the electro-optical cell can be considerably improved when the nematic layer is reoriented from the initially homeoplanar director configuration into the twisted state. Besides, a method to shorten the relaxation time is demonstrated by using a controlling pulse with a bipolar waveform. (C)2014 Optical Society of America

Аннотация: The transmittance anisotropy of a composite polymer-liquid-crystal film has been studied as it varies with the degree to which it is elongated. The composite film includes polyvinyl alcohol, the nematic liquid crystal 4-n-pentyl-4'-cyanobiphenyl, and the surfeiting cetyltrimethylammonium bromide, which initiates homeotropic adhesion of the nematic to the surface of the polymer. It is shown that, when the film is uniaxially stretched, the transmittance of the orthogonally polarized component of directly transmitted radiation and accordingly the degree of polarization abruptly increase, reaching saturation when it is stretched to twice its length. Such variation of the film's macroscopic optical properties can be caused by an orientational-structural transition to a homogeneous configuration of the director in deformed droplets of the nematic and makes it possible to substantially improve the optical characteristics of light polarizers based on such composite media.

Аннотация: We have prepared thin indium oxide films by the autowave oxidation reaction. Measurements of temperature dependence of resistivity, Hall carrier concentration and Hall mobility have been conducted in the temperature range 5-272 K. Before ultraviolet (UV) irradiation, the indium oxide film had a semiconductor-like temperature dependence of resistivity. and the ratio of rho (5 K)/rho(272 K) was very limited (similar to 1.2). It was found that after UV irradiation of the In2O3 film, the metal-semiconductor transition (MST) was observed at similar to 100 K. To show that this MST is reversible and repeatable, two full cycles of 'absence of MST-presence of MST' have been done using UV irradiation (photoreduction) as the induced mechanism and exposure to an oxygen environment as the reversible mechanism, respectively. MST in transparent conducting oxide (TCO) is possibly associated with the undoped structure of metal oxide, which has some disorder of oxygen vacancies. It was suggested that reversible UV induced metal-semiconductor transition would occur in other TCOs.

Аннотация: A one-dimensional asymmetric photonic crystal with dual-frequency liquid crystal as a central defect layer was demonstrated. Such asymmetric structure was characterized by the dramatic increase in intensity of the electric field of light localized at the overlapped photonic bandgap edges, thereby enhancing the observed transmittance of the spectral windows originating from the defect layer. The defect layer was made of a dual-mode liquid crystal that exhibited not only electrical tunability and switchability but also optical bistability. Consequently, tunable and bistable defect modes can be realized in the photonic structure. This asymmetric photonic crystal structure is promising and should be further explored for photonic device applications. (C) 2014 Optical Society of America
