In comparison with the well-known E-plane filters on homogeneous resonators, the stopband of proposed structure is much wider and has higher attenuation. Significant improvement of these characteristics was achieved by a slight change in the topology of the filter resonators - the implementation of each resonator was realized using fin-lines of significantly different slot widths. These changes in topology dramatically change the frequency response of the resonators. In resonators with a significant predominance of the length of the low-impedance fin-line section, an increase in the bandwidth between the main and high order resonances can exceed 50% compared to homogeneous resonator. This is accompanied by a significant increase in the attenuation level in this frequency band and the appearance on the attenuation pole, the frequency of which can vary over a wide range by changing the impedance of the low-impedance section. The filter synthesis procedure is based on the use of a modified technique with K-inverters. The size of the elements required to implement the inverter specifications were calculated using a FDTD simulation. The two-resonator filter with a central frequency of 17.25 GHz, with a bandwidth of 300 MHz was calculated and manufactured; it showed losses in the passband of the order of 1 dB, losses of higher than 30 dB up to 29.5 GHz in the stopband, and a maximum attenuation of 45 dB in the stopband. In comparison, the calculated values for a two-resonator filter using homogeneous resonators with the same specifications produces the same stopband losses only up to 21 GHz, a maximum loss of 32 dB, and moreover, the proposed filter has a reduction in size of 25%.","PeriodicalId":210314,"journal":{"name":"2020 IEEE 40th International Conference on Electronics and Nanotechnology (ELNANO)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121530691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to structure of cellulose it can be incorporate with various additives, in particular oxides, in order to produce composites with improved physico-chemical properties. This paper reports data on preparation and characterization of composites based on micro/nanocrystalline cellulose with ZrO2 nanopaticles codoped with europium and fluorine ions. Morphology, dielectric and luminescence properties of the composites have been studied and analyzed together with data on properties of the starting components and literature data. It was found that samples consist of tightly packed cellulose plates of 2 – 20 µm in size. The small oxide particles are generally located inside the cellulose plates, while the larger ones and agglomerates are found on the plate's surfaces. Chemical elements analysis has shown that carbon and oxygen with average content about 71 and 29 at. %, respectively, are the main components in the most areas of the plates. Degrees of crystallinity for the samples were estimated from XRD patterns and obtained values are in the 58 - 61 % range. The photoluminescence spectra of composites consist of wide band with maxima near 480 nm related with cellulose host and weak bands of Eu3+ ions luminescence peaks in 580–700 nm spectral region. In case of excitation at 393nm the CIE chromaticity coordinates of composites are moving from (x=0.211, y=0.261) for pure cellulose to (x=0.250, y=0.343) for composite with 10 wt. % of ZrO2:Eu,F in composite. Dielectric relaxations were observed for real and imaginary part of dielectric permittivity near – 50°C and ascribed to reorientation of methyl groups on the micro/nanocellulose crystallites surfaces.","PeriodicalId":210314,"journal":{"name":"2020 IEEE 40th International Conference on Electronics and Nanotechnology (ELNANO)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130019450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
