Аннотация: The resistivity and the optical absorbtion spectra of single crystal alpha-MnS are studied in the temperature range 80-300 K along two directions [100] and [111]. Strong anisotropy of the resistivity, and the shift of absorbtion spectra band edge below T < 160 K are explained in terms of model involving delocalized holes in 3d-band manganese ions interacting with localized spins by using the sd-model.

Аннотация: Noncollinear second-harmonic generation from two ultrashort pulses intersecting in a nonlinear medium is studied in spectral and time domains. We derive analytical expressions for the second-harmonic (SH) amplitude in crystals of finite thickness neglecting diffraction. The contribution from characteristics of the fundamental radiation and interaction geometry to the process is analyzed. In addition, refined phase-matching conditions are obtained. We find that the spectral bandwidth is determined by the intersection angle and can be enlarged. The SH pulse duration can be optimized by varying the fundamental beam size and the intersection angle. It is found that the SH beam excited by a Gaussian fundamental beam becomes elliptical. It is shown that the fundamental pulse duration can be readily characterized with single pulses by means of measuring the ellipticity of the SH beam profile. The approach developed can potentially be used to calculate parametric interactions of fundamental pulses with an arbitrary spectrum. © 2016 Optical Society of America.

microstrip diplexer -- bandwidth
Аннотация: The structure of microwave diplexers based on two-dimensional (2D) electromagnetic crystals of various size has been theoretically and experimentally investigated. In the proposed devices with high-frequency selective properties two rows of microstrip quarter-wave resonators electromagnetically connected with each other and with the input of the strip conductor are used. This allows splitting the signal into two channels.

High-quality compact interdigital microstrip resonator and its application to bandpass filter / B. Belyaev [et al.] // Prog. Electromagn. Res. C : Proceedings. - 2017. - Vol. 72. - P. 91-103. - Cited References: 27 . - ISSN 1937-8718

Аннотация: A compact microstrip resonator based on the interdigital structure is proposed. The resonator has several times higher unloaded quality factor compared to similar resonators presented previously and can even reach the Q-factor of a regular λ/4 resonator. The size of the resonator can be significantly reduced with a substantial increase in quality factor by incrementing the number of fingers in the interdigital structure. In addition, for each gap between the fingers, there exist an optimal number of fingers that correspond to the maximum Q-factor. An extension of the upper stopband for a bandpass filter designed using the resonator can be achieved by the interconnection of the fingers in each of the comb structures. The simulation results are proven by fabricated resonators and a fourpole bandpass filter. For the central frequency of 2000 MHz and 16.2% fractional bandwidth, the lateral size of the filter is only 11.5mm × 3.8 mm for alumina substrate (eps = 9.8). The filter has an upper stopband up to 5.8f0 at the level −40 dB.

Аннотация: The diplexers based on 2D electromagnetic crystal are investigated with the help of the numerical electrodynamic analysis of 3D models. The input half-wave resonator has rolled up strip conductor in the claimed microstrip designs tuned with nearly adjacent bandwidths. It allows to coordinate channels rather easily. Such resonator in the first two-channel device at the same time interacts with pair of quarter-wave resonators having strip conductors in the form of the Russian letter «П». In the second two-channel device it interacts similarly, with pair of resonators with strip conductors in the form of a letter «Ш». Build-up of number of periodically located rectangular portions of strip conductors in adjacent resonators allows to increase in proportion number of the resonances participating in formation of both low-frequency, and high-frequency bandwidths. At the same time in amplitude-frequency characteristics of diplexers growth of the steepness of slopes of adjacent bandwidths and gain suppression of power at frequencies of stop bands are observed. © 2016 IEEE.

Аннотация: Ten microstrip bandpass filters with wide high-frequency stop band are investigated with the help of the numerical electrodynamic analysis of 3D models. From each resonator bandwidth of the offered filters tuned with a relative width Δf/f0=20% is formed by one lowest oscillations mode only. However at all microwave devices the extended high-frequency stop band is observed due to large leap of lines portions wave drags. Build-up of number of resonators in filters up to 6 order is resulted by growth of the steepness of slopes bandwidth and gain suppression of power at frequencies of stop bands. The width of high-frequency stop band at miniaturization of microstrip devices is reducing.

Аннотация: This paper presents a ferrite tunable waveguide filter showing high Qu and high tunability in X-band. A new type of waveguide cavity resonator with an H102 operating mode was proposed for the creation of a low-loss, two-pole filter. The filter results in an insertion loss of 3.6-4.1 dB over the tuning range 8.74-9.63 GHz with a relative bandwidth of 0.92-0.79% and biasing magnetic field 0-600 Oe. This design demonstrates an unloaded quality factor of 380-396 over the tunable frequency range. © 2016 IEEE.

Аннотация: Regular arrays of plasmonic nanoparticles have brought significant attention over the last decade due to their ability to support localized surface plasmons (LSPs) and exhibit diffractive grating behavior simultaneously. For a specific set of parameters (i.e., period, particle shape, size, and material), it is possible to generate super-narrow surface lattice resonances (SLRs) that are caused by interference of the LSP and the grating Rayleigh anomaly. In this letter, we propose plasmonic structures based on regular 2D arrays of TiN nanodisks to generate high-Q SLRs in an important telecommunication range, which is quite difficult to achieve with conventional plasmonic materials. The position of the SLR peak can be tailored within the whole telecommunication bandwidth (from ≈ 1.26 μm to ≈ 1.62 μm) by varying the lattice period, while the Q-factor is controlled by changing nanodisk sizes. We show that the Q-factor of SLRs can reach a value of 2 × 103, which is the highest reported Q-factor for SLRs at telecommunication wavelengths so far. Tunability of optical properties, refractory behavior, and low-cost fabrication of TiN nanoparticles paves the way for manufacturing cheap nanostructures with extremely stable and adjustable electromagnetic response at telecommunication wavelengths for a large number of applications.

Аннотация: Multilayer photonic crystal structures with bleaching layers are being investigated. In order to calculate the characteristics of ultra-wideband filters on their basis, T-lines lossless model was used. Amplitude-frequency characteristics for the synthesized filters of 5th, 11th and 17th orders are given. It is proved that by a significant increase in filter N order, the difference between the connection coefficients of central resonators' layers' becomes negligible. This makes it possible to develop 27-order filter, in which almost half of the layers are realized by periodic interchange of only two identical high-contrast materials. The investigated band-pass filters, including the ones on a glass substrate, have high frequency-selective properties at a relative bandwidth of 80%.

Resonators -- Frequency-selective properties -- High frequency HF -- Microwave structures -- Multimode resonators -- Quarter wave resonators -- Relative bandwidth -- Single-mode resonators
Аннотация: A new approach allowing to improve frequency-selective properties for a fixed order of N filter is suggested. In all the studies, conducted with the help of numerical electrodynamic analysis of 3D models of microstrip filters based on a multimode resonator, the same substrate with dielectric constant ϵ=2.8 and thickness h=2 mm (material - FLAN) was used in calculations. The central bandpass frequency of microwave structures f 0≈1.4 GHz was registered and as well as relative bandwidth Δf/f o≈80%. The strip conductor of central multimode resonator in six studied filters of the sixth and eighth orders has the shape of an irregular meander being electromagnetically connected with four single-mode resonators, a pair of which is located to the left of it, and the other pair is to the right. It is shown that in single-mode quarter-wave resonators building-up the number of portions of identical parallel strip conductors, connected to a screen at one end and connected with each other by a strip conductor jumper, can increase the power of suppression at low-frequency stop band by more than 15 dB, as well as near high-frequency slope of passband by more than 10 dB. Therefore, the level of maximums of return losses in the passband of wideband bandpass filter ranges within a few dB.

chemical substitution -- green-emitting phosphor -- narrow-band emission -- site engineering
Аннотация: It remains a critical challenge to develop narrow-band emitters for wide color gamut displays. Herein, it is designed by the selective site occupancy engineering and an unprecedented narrow-band green-emitting phosphor is prepared through chemical substitution. By introducing Ga3+ ions into Sr2LiAlO4:Eu2+ phosphor, the distribution of Eu2+ ions in Sr1 and Sr2 sites is effectively controlled, and only one type of luminescent centers Eu2+(Sr1) is remained in Sr2LiAl0.6Ga0.4O4:Eu2+ due to the compression effect of Sr2O8 polyhedra. Sr2LiAl0.6Ga0.4O4:Eu2+ phosphor presents an extremely narrow-band green emission centered at 512 nm with a full-width at half-maximum of only 40 nm. The wide color gamut (107% National Television System Committee) of the as-fabricated white liquid crystal displays and the vivid figures captured from the projector demonstrate the potential application of narrow-band emitter for wide-color gamut displays. This work provides the design principles of realizing narrow-band emission by selective site occupancy engineering and can set the stage for the exploring of Eu2+-activated phosphor for high definition displays.
