S-band (2.7–3.1 GHz bandwidth) microstrip bandpass filters of several four-resonator structures for pre-selectors of active phase array radar systems are designed, produced and measured. A conventional parallel-coupled filter is produced and measured for comparison. Measurement results confirm good performance of used approach.","PeriodicalId":296618,"journal":{"name":"2018 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"329 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114371949","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}

For different cases, the minimum distance between the Shannon curve and the point which coordinates are the values of the spectral and energy efficiency is calculated. The use of polar codes allows to get closer to the Shannon limit of 11%. Compared to “classic” BPSK signals, optimal signals with polar coding come up with the gain about 86%.","PeriodicalId":296618,"journal":{"name":"2018 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116286005","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}

The origins of low work function effect are considered and interpreted as a repercussion of surface modification and structure alteration on the composite material properties. The significant decrease in the effective electron work function to an anomalously low value of 1 eV is obtained with a perforated nickel anode functionalized with nanosized graphene layers. SEM X-ray microanalysis of the TEC collector surface is performed, the mechanism of the anode work function lowering effect is considered. Raman spectroscopy technique is utilized in order to investigate the surface structure properties of PS-based composite layers (PS/Ag).
