The novel solution of training phase LMS (least mean square) filter, which has the best filtering characteristics, is described and simulated.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"75 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127417906","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}

Such models provide exact full-wave semi-analytical solutions for an arbitrary interconnection system, on the other hand, they are represented in a circuit form and, thus, can be implemented in common circuit simulators. The paper derives a general DGF-PEEC formulation that can be applied to all types of MPIE with dyadic Green's functions. Based on this concept, the PEEC model for interconnections in layered media is developed, and verified with the help of a MoM code and by measurements as well.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129131969","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}

Therefore based on an introduced via model for a through-hole via its scattering parameters are extracted using a de-embedding algorithm. After the following calculation of the via model elements with the two-port theory, the extracted impedances are inserted in a known formula for the power-bus impedance. In addition, it is shown how the signal return current acts as an excitation source of the waveguide modes within the power-bus.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127305758","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}

In order to avoid the use the numerical methods and to permit a simplified modelling, we used a concept founded on Hertziens dipoles method and modified images theory. We treated the applications where we put in evidence the defect on buried grid by confronting the magnetic field radiated at the interface with and without defect, along a profile or on a relief. Indeed the cartography of the electromagnetic field proves to be a very revealing element of the changes that can operate themselves in the time or by current strokes.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131669602","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}

For that purpose, we propose a description of the methodology used to predict the induced levels on the BUS for typical scenario derived from aircraft topology. Models needed to perform such a simulation are coupler model, transformer model, cable model, injection model. To validate the simulation chain before the exploitation, we perform two kind of validations i.e. simulations / measurement comparisons: one at component level and the other one on a setup representative of aircraft. The predicting tool used in this study is Aseris NET. It solves network equations in the frequency domain with multiconductor transmission lines method.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134262240","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 second concerns possible coupling from inside the aircraft to different relevant aircraft navigation and communication antennas which are mounted outside the aircraft along the fuselage.

The statistical model was validated by a discrete approach and a semi-empirical model was derived to calculate the power transmitted inside a nested RC through an aperture covered by a lossy thin slab.

The metallic sheaths of such cables are connected to the grounding systems and may have significant grounding effects. In case of uncoated metallic sheathed cables they act as extended grounding electrodes while coated cables connect different grounding systems at transformer stations and customer premises. This usually improves the grounding conditions at the source transformer station but potentially dangerous voltages might be transferred to other locations. This paper analyses the lightning current distribution between the local grounding system, stoked by lightning, and connected cable metal sheaths. It is shown that after the first tens of microseconds local grounding system loses its function and cables take away nearly all lightning current.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128422759","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 represents a clear improvement with respect to the present situation of EMC standards based upon simple qualitative checks, which do not offer any warranty of safety because it is not clear how far the DUT is from its susceptibility threshold: even if the device under test is declared to be immune in normal operative conditions it may happen that a simple environmental effect such as temperature variation has catastrophic consequences.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117191227","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}
