TDVF is the counterpart of the vector fitting (VF) [2] in the time domain (TD), but it is not popular as VF due to the fact that a technique for estimating the order of the rational function fit for TDVF is not available even though the accuracy of the model built by TDVF strongly depends on the choice of the order of the rational function fit. This paper introduces a new methodology toward an efficient and robust whole channel simulation using the TDVF algorithm which is equipped with a sound estimate for the order of the rational function fit. This method significantly reduces the computational resource, while enhances the model accuracy. As a validation study, TDVF equipped with the order estimation method was applied for modelling a socket component in multi-Gbps interconnects.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120847721","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}

Numerical simulations are presented to analyse the influence of the soil stratification on the above-ground lightning electromagnetic field components.

The first one is totally analytical and is based on the transmission line theory and Taylor model. The second one uses the insertion of equivalent sources into an electromagnetic simulation tool.

This paper proposes two simple analytical formulations for effective permittivity and permeability of magneto-dielectric composites as functions of frequency and concentration. The first new proposed mixing rule is based on the Ghosh-Fuchs theory, which gives good agreement with the measured permittivity and permeability for composites containing magnetic alloy powders. This approach employs the Bergman-Milton concept of spectral function. Herein, the spectral function typical for the Bruggeman effective medium theory, also known as the Bruggeman symmetric rule (BSR), is chosen. This spectral function is composed using two fitting parameters: an averaged shape factor of inclusions, and the percolation threshold. These fitting parameters are found from the concentration dependence of permittivity, and then they are used to retrieve frequency dependence of permeability. The proposed mixing law is valid for nearly spherical inclusions in the composite, e.g., crumbs. Another analytical model proposed in this work can be applied to predict effective permeability of composites containing magnetic inclusions. It is based on the Bruggeman asymmetric rule (BAR), which has been modified in such a way that it takes into account shape factors of magnetic inclusions, in particular, randomly oriented platelets.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124365076","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}
