The analytical expressions are determined, and characteristics of antennas with straight metal dipoles and with in-phase radiators of the same dimensions are calculated. The advantage of using in-phase radiators is demonstrated. It is shown that the log-periodic antennas of radiators with in-phase current distribution allow to decrease the antenna length and to provide the high directivity in a wide frequency range. The problem of optimization of considered antennas by methods of mathematical programming is stated.","PeriodicalId":321624,"journal":{"name":"2017 XI International Conference on Antenna Theory and Techniques (ICATT)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126074130","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 system is supposed to be longitudinally magnetized, i.e. the static external magnetic field is applied along the axis of the guide, perpendicularly to the layers of the structure. The system is considered to be in the subwavelength regime, and the relative effective permittivity and permeability of the waveguide filling are introduced. The waveguide dispersion equation and its eigenmodes are derived. Unique dispersion characteristics of supported hybrid modes are investigated. It is shown that simultaneous presence of gyromagnetic and gyroelectric eifects in the waveguide system can gain a substantial control under the dispersion characteristics and field distributions of the supported modes.","PeriodicalId":321624,"journal":{"name":"2017 XI International Conference on Antenna Theory and Techniques (ICATT)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125748253","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}

As before, algorithms of processing of pulse signal reflected by plane structures which was proposed by the Authors constitute the method base. The advantages of this approach are combination of the information content of the UWB pulse signals and the efficiency of algorithms for solving inverse problems. For processing and interpretation of the experimental data, the Newton-Kantorovich scheme in the frequency range is used. Using developed software, series of experiments on the processing of GPR pulse signals in sensing plane-layered medium (road pavement) is carried out. The obtained results allow to optimize values of the pulse signal parameters. Also, the obtained results can be used in biomedical research and in non-destructive testing of industrial facilities.","PeriodicalId":321624,"journal":{"name":"2017 XI International Conference on Antenna Theory and Techniques (ICATT)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124361290","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}

They allow improving the functional characteristics of the arrangements made on their base. Nanostructures construction with preset properties is important for design of sub-THz and THz radioelectronics.
