The results obtained correspond to the upper part (consisting of two separate areas) relevant to small and large values of the off-diagonal ferrite permeability tensor element, of the frequency band in which the structure exhibits phase shifting properties. They complement previous ones for the lower part of the same. The joint consideration of the new and earlier outcomes shows that the phase shift increases almost linearly with the tensor element (is almost proportional to the reciprocal of normalized guide radius) in the whole band, if the radius (the tensor element) is fixed.","PeriodicalId":104769,"journal":{"name":"2010 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"489 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":"123035103","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 expansion has been derived analytically by the authors in a recent article [SIAM J. Appl. Math., 70 (2010), pp. 2329–2352] with the aid of the two-interval Sturm-Liouville theory. In our effort to implement numerically the aforesaid expansion we discovered a numerical instability on the spherical surface which is centered at the vertex of the cone and passes through the point source. In this paper we present an analytical way of removing that instability. Furthermore, we propose some numerical methods for calculating the terms of the eigenfunction expansion and we present some numerical results in the form of equipotential contour plots.","PeriodicalId":104769,"journal":{"name":"2010 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"31 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":"114563647","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}
