Conductivity measurements were performed, structural and microstructural features of materials were studied. It has been found that concentrations of germanium oxide and fluorides significantly affect the degree of absorption of microwave energy by samples. Absorption spectra close to linear ones at levels from 0-3 dB to 12-14 dB were obtained in the whole investigated frequency range for various materials. Some increase in the absorption (5-10%) of energy by these composite materials under the influence of a weak (H≈300 kOe) constant magnetic field was revealed. The spectra of the integral radiation of the electric field were measured with the composites with the lowest conductivity. Prospective areas of work have been outlined for obtaining broadband radio-absorbing composite materials.","PeriodicalId":158616,"journal":{"name":"2019 Radiation and Scattering of Electromagnetic Waves (RSEMW)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115321297","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 proposed antenna array consists of 2 subarrays, subarray consists of 16 horn radiators. The subarray based on waveguide continuous transverse stubs is fed by a waveguide binary power divider. The CTS subarray for scanning antenna array was calculated and researched. The developed subarray has compact structure, light weight, manufacturability and high efficiency. A beam-scanning range of ± 90° is achieved by mechanically rotating subarrays around its axes at the same angles. The calculated aperture efficiency exceeds 55% in the entire working frequency band. The proposed scanning antenna array with high efficiency can be used for satellite communication terminals and radar systems.","PeriodicalId":158616,"journal":{"name":"2019 Radiation and Scattering of Electromagnetic Waves (RSEMW)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121369728","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}

This model is intended for wireless communication networks of UHF, L and S bands, including mobile networks of the fourth-generation (4G). A technique of testing of numerical simulation methods for frequency synthesizers in the time domain is proposed. This technique of testing is based on the research of computational errors for quality parameters of transient processes and allows realizing a comparative analysis of numerical simulation methods for frequency synthesizers. Numerical simulation of frequency synthesizers was made in Matlab-Simulink package with use of various numerical methods for solving ordinary differential equations.
