Аннотация: Using data on the structure of plant leaves, specific features of light propagation in biophotoniccrystal structures have been established by the transfer matrix method. Splitting of the stopband in two bands has been found. The density of photonic states and the electromagnetic field value have been calculated. The occurrence of two photosystems (splitting of the stopband in two bands), the peculiarity of the long-wavelength quantum yield and its enhancement (Emerson effect), and water dissociation in the soft mode due to an increase in the electromagnetic field on the layers are explained.

Аннотация: A multimode resonator is proposed, containing five resonant modes that are incorporated in the passband forming. The structure is based on a dielectric substrate suspended in a metallic case that allows solving problem of electromagnetic compatibility. Due to features of the resonator's structure, several higher modes do not excite that significantly improve the performance of the filter's stopband. The resonator advantages are proved on the ultra-wide bandpass filter (101%) with small overall size (0.11λ 0×0.06λ 0×0.03λ 0) and good stopband performance (first spurious band locates at 8 GHz, suppression is 80 dB).

Bandpass filter -- meander -- stopband
Аннотация: The constructions of bandpass filters with irregular quarter-wave resonators are suggested. Due to the high jump of the wave resistance in line segments the microstrip structures have extended high-frequency stopbands. Different alternatives for the location of resonators with a conductor in the form of meander on dielectric substrate were studied. In this regard the use of codirectional resonators helps to improve frequency-selective properties of microwave filters. © 2017 IEEE.

A method of stopband widening in BPF based on two-conductor suspended-substrate resonators / A. A. Leksikov [et al.] // Prog. Electromagn. Res. Lett. - 2018. - Vol. 72. - P. 11-16, DOI 10.2528/PIERL17102302. - Cited References: 10 . - ISSN 1937-6480

Fourth order -- Microwave bandpass filter -- Stopband -- Stripline resonators -- Suspended substrates -- Wide upper stopband
Аннотация: A method aiming to widen the upper stopband in a microwave bandpass filter based on two-conductor suspended-substrate stripline resonators is described in this letter. Applicability of the method is illustrated by simulating and fabricating fourth-order filter that has a very wide upper stopband: Δfstop/f0 = 7.92 measured at a level -50 dB, which is achieved because the widths of the inner resonators in the structure are 1.4 times greater than that of the outer ones.

Кл.слова (ненормированные):
filter -- frequency selective surface -- grating -- multilayer design -- polarizer
Аннотация: We propose a multilayer bandpass filter in which every resonator consists of two identical dielectric layers separated by a grating of parallel strip conductors. The resonators themselves are separated from each other and from the ambient space by gratings of strip conductors with an axis orthogonal to the axis of the gratings inside the resonators. The proposed filter construction acts at the same time as a polarizer. The device frequency response computed with use of the provided simple formulas is in a good qualitative agreement with numerical electromagnetic analysis of its 3D model.

Design for a self-packaged aLl-PCB wideband filter with good stopband performance / B. A. Belyaev, A. M. Serzhantov, Y. F. Balva [et al.] // IEEE Trans. Compon. Packag. Manufact.

FEFE-2020-0013 . - ISSN 2156-3950
Кл.слова (ненормированные):
wideband filter -- printed circuit board technology -- wide stopband -- bandpass filter
Аннотация: A new design of a self-packaged all-PCB wideband filter based on the cascade connection of high-pass and low-pass filters is presented. The novel low-pass and high-pass quasi-lumped filter structure differs from the known ones by the existence of cross-coupling between elements producing transmission zeroes at the desired frequency. It is shown that high order structures make it possible to design a wideband filter having the number of transmission zeros in the low-frequency stopband equal to the order of the applied high-pass filter and the number of transmission zeros in the high-frequency stopband equal to half the order of the low-pass filter. An implementation of two-layer metallization of the capacitor plates made it possible to manufacture all three types of filters using the common technology of multilayer printed circuit boards with a good coincidence of the characteristics of the model and the fabricated filters. The filter fabricated using materials with a rather low-quality factor (F4BM/RO4450B/RO4003C) has demonstrated a good performance: the central frequency is 0.99 GHz, the 1 dB fractional bandwidth is 152%, the minimum in-band loss is 0.3 dB, the selectivity (Δf30dB/Δf3dB) is 1.21, and the 40-dB stopband width is 6.16f0.

Microstrip rejecting bandstop filter / A. A. Leksikov, A. O. Afonin, A. A.

Кл.слова (ненормированные):
microstrip -- BSF -- through line -- resonator -- rejection -- stopband -- substrate -- shielding
Аннотация: The paper is devoted to simulation, designing and fabrication of a microstrip 5-order bandstop rejecting filter. The bandstop filter uses classic schem, e.g. it consists of a microstrip through (common) line whose ends serve input and output ports. In the vicinity of the line a number of microstrip rejecting resonators locate, in our case five S-shaped resonators. They electromagnetically interact with the line, that forces signals, having frequenscies, bieng equal to the resonant ones, to reject (reflect) from a device. Dielectric substrate of the device has thickness 1.0 mm, and other sizes are 44.0×20.0 mm 2 . The filter described in this work has shielding. In a band 1480 MHz …1499 MHz rejection exceeds 50 dB. Transmission bands at a level –2 dB are 0…1437 MHz and 1563 MHz…3000 MHz lower and upper correspondingly. Return loss in the passbands does not exceed –16 dB (VSWR≤1.4). Good agreement is observed between simulated and experimental data. Fabricated filter has small size.

Кл.слова (ненормированные):
lowpass filter -- substrate -- stripline resonator -- stopband
Аннотация: A new miniature design of a highly selective lowpass filter based on a suspended substrate with a two-sided stripline pattern has been developed. The filter frequency response slope (cutoff attenuation rate) and stopband attenuation depth are determined by transmission zeros, the number of which is equal to the filter order. An experimental prototype of a fifth-order lowpass filter on 0.5-mm-thick alumina substrate with dielectric permittivity ε = 9.8 has been synthesized with the aid of numerical electrodynamic analysis of a three-dimensional model. The cutoff frequency of the filter passband at a –1-dB level is fc = 1.75 GHz. The stopband width at a –100-dB attenuation level reaches 4.4fc.
