The presented mathematical model applies scattering and transmission matrices of the structure elements for the calculation of general scattering matrix of the whole waveguide section. Depending on linear polarization type of the fundamental mode the irises are simulated as inductances or capacitances, which are connected in parallel into the equivalent transmission line. Two antiphase posts in a square waveguide are modeled as a parallel resonant circuit in the equivalent transmission line. Using the developed mathematical model the matching characteristics and differential phase shift of square waveguide sections with two irises and two posts were calculated theoretically. In order to check the performance of developed mathematical model the simulations of the same waveguide sections were performed using finite integration technique. Presented waveguide sections can be tuned by changing the length of their posts. Both optimized designs of square waveguide sections with two irises and two posts provide voltage standing wave ratio less than 1.4 for both polarizations. Differential phase shifts of developed polarizer sections are 30°±0.7° and 45°±1.75°. Therefore, suggested new simple mathematical technique for calculation of characteristics of the waveguide sections with irises and antiphase posts can be widely used for the development of new tunable waveguide filters, phase shifters and polarization processing devices.","PeriodicalId":312916,"journal":{"name":"2020 IEEE 2nd International Conference on Advanced Trends in Information Theory (ATIT)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121461918","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 method is based on the method of differential transformations and approximation of the spectral function in the basis of the transfer functions of the second order resonant units.To detect the signals of the secret means of obtaining information, it is proposed to determine at the first stage the spectrum of signals. The signals of the means of secretly obtaining information can be approximated by differential Taylor transformations, or more simply by T transformations. Moreover, differential images are differential T - spectra. Subsequently, an approximation of the already spectral function is performed in order to extract the components of the essential signal.In order to confirm the proposed technique, modeling of the exponential function was performed.

Graphic materials fully confirm the reliability of the proposed method.","PeriodicalId":312916,"journal":{"name":"2020 IEEE 2nd International Conference on Advanced Trends in Information Theory (ATIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122358733","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 neural network architecture is proposed as a promising approach to increase the accuracy of the 2m temperature forecast given by the COSMO regional model. This architecture allows predicting errors of the atmospheric model forecasts with their further corrections. Experiments are conducted with different histories of regional model errors. The number of epochs after which network overfitting happens is determined. It is shown that the proposed architecture makes it possible to achieve an improvement of a 2m temperature forecast in approximately 50% of cases.","PeriodicalId":312916,"journal":{"name":"2020 IEEE 2nd International Conference on Advanced Trends in Information Theory (ATIT)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124606459","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}
