Exact solutions for complex amplitudes of reflected and transmitted waves are found by method of transmission matrices. Influence of connection of lumped elements on resonance properties of Bragg resonators is investigated. Optimal values of reactive conductivity for different values of thickness of central layer are found. Shifting of resonance frequency for nonoptimal values of conductivity of shunt element is considered. Hysteresis behavior is observed for case of Kerr nonlinearity.","PeriodicalId":104769,"journal":{"name":"2010 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133610440","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}

FBC involves fractional derivative of tangential field components. FBC can be treated as intermediate case between well known boundary conditions for perfectly electric conductor (PEC) and perfectly magnetic conductor (PMC). A method to solve two-dimensional problems of scattering of E-polarized plane wave on a strip and half plane with FBC is proposed. The considered problems are reduced to coupled integral equations which are discretized using orthogonal polynomials. The method allows to obtain physical characteristics with any desired accuracy. One important feature of the considered integral equations is noted: these equations can be solved analytically for one special value of the fractional order equal to 0.5 for any frequency.","PeriodicalId":104769,"journal":{"name":"2010 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134480996","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}
