The FDFD formulation for ferrite devices is built from the integral form of Maxwell's equations. After implementing all the boundary conditions, the finite-difference formulation is concluded as an eigen equation and then constructed by a highly sparse matrix. By solving the matrix eigen equation, the dispersion characteristics of ferrite devices for a given frequency can be obtained. In order to verify the validity of the proposed method, an infinite ferrite filled waveguide is examined and then the numerical results are compared to the theoretical and 3-D finite-difference time-domain (FDTD) numerical results.","PeriodicalId":156210,"journal":{"name":"2003 33rd European Microwave Conference, 2003","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116442799","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 main aim of the new method is to reduce the number of sample iterations for mobile communication front-end modules. The main elements of the method include, extracting accurate component models, incorporating into the models an automated layout generation facility and linking the layout to an EM simulator for final analysis. The component models discussed include equivalent circuits, EM generated databases and neural network models. Models up to 18GHz have been produced and verified by measurements. The influence of manufacturing process tolerances have been studied and incorporated into the models. Unwanted coupling mechanisms are discussed and examples of the coupling levels between surface pads and embedded components are presented for the first time. The predicted and measured results of a GSM/DCS antenna switch module are presented. The agreement between the predicted response and the measured response is excellent.","PeriodicalId":156210,"journal":{"name":"2003 33rd European Microwave Conference, 2003","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123643571","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}
