Also a noise superimposed to the signal has been considered. Parameters relevant to human exposure have been calculated following the ICNIRP Guidelines. A schematic operative diagram for metal inert gas welding applications is proposed; an experimental set-up has been built and the obtained results are reported.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"23 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":"130414785","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 relationship between different unbalance parameters and the resulting type of radiated field is shown and could be the basis for defining appropriated test conditions, when characterising BPL modems and systems.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"85 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":"115848438","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 approach accounts for the corresponding impulse responses relating the feeding port signal to any vector field quantity at arbitrary positions within the cell. The investigations are conducted for a large GTEM cell by evaluating its simulated EM field when excited by an ultra-wideband (UWB) voltage pulse. For the field magnitude in question, the impulse response in each field component is numerically calculated by means of inverse convolution. Thus, the field components are determined for arbitrary excitation signals by convolution without need for further 3D simulations of the GTEM cell. The impulse response is verified by a comparison between convoluted results and a full wave simulation.","PeriodicalId":133902,"journal":{"name":"2008 International Symposium on Electromagnetic Compatibility - EMC Europe","volume":"74 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":"128372818","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}
