The strips of the gratings are made of PEC-like material of nonzero thickness. When the crossing angle of this structure changes from 90° to 0° the frequency dependences of the scattered powers reveal the resonances, the frequencies of which depend on the crossing angle of the gratings in a wide frequency range. Experimental investigation of the crossed strip gratings in microwave frequency range shows a good coincidence with the theory based on Integral Functional Method.","PeriodicalId":269665,"journal":{"name":"2018 IEEE 38th International Conference on Electronics and Nanotechnology (ELNANO)","volume":"127 47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124037811","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 mathematical models and algorithms are playing a major part in evolution of electronic systems. Therefore, the improving of models and algorithms is fundamental problem in further systems development. The algorithm for information support an automated system has been studied. The inertia constant, which representing dynamic property of electric generator, has been founded by analyzing components of mathematical model, describing dynamics of power system. It should not be forgotten, however, that the most of the distributed generation control systems have focus on power control (P and Q) to achieve reliable operation of the local grid. The suggestions about supplementing control system algorithm of power system with distributed generation sources for concern of their dynamic properties are made. The supplementing consists of including information-feedback system (IFS) module on all hierarchical levels. This module includes data and algorithm of analyzing the stability.
