However, the cable harness used on automotive vehicles shows a vast amount of different wire lengths. Emission measurements can thus only give limited information about the behavior of the system connected to a real harness system. Especially within the filter development process, the later connected cable harness can not be easily considered. In the worst case, this leads to high radio disturbance levels within the vehicle, however the module passed all component tests in respect to CISPR25. The paper gives an overview how the connected harness influences the filter attenuation and how to consider the effect during the development process.","PeriodicalId":192851,"journal":{"name":"2009 20th International Zurich Symposium on Electromagnetic Compatibility","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123935566","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}

First, we try to confirm the validity of the measurement method using the semi-anechoic chamber. The examination including the ground plane is necessary to specify about the emission standard of the entire photovoltaic generation system. We compared with the measurement and the calculation results for the radiation and the induction characteristics by using the dipole antenna of our own making, and the validity of the measurement and the calculation method was confirmed. Next, we measured the induced voltages of the PV cell actually used, and those are compared with each other. Finally, the calculated induction characteristic for the horizontal direction on the side face agrees with that measured.","PeriodicalId":192851,"journal":{"name":"2009 20th International Zurich Symposium on Electromagnetic Compatibility","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127626407","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}

Specific absorption rate (SAR) and current density were analyzed by an electromagnetic simulator in a model consisting of a primary coil and a human trunk that included eighteen different organs. SAR and current density as a function of frequency were analyzed. The SAR was maximized at muscle and fat, and was below the basic restrictions of the International Commission on Non Ionizing Radiation Protection (ICNIRP). At the same time, the results for current density were maximized at muscle and intestine, and were below the ICNIRP basic restrictions, indicating that it was possible to safely transmit energy up to 30 mW at the frequency of 300-600 kHz.","PeriodicalId":192851,"journal":{"name":"2009 20th International Zurich Symposium on Electromagnetic Compatibility","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127228585","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, electromagnetic interference (EMI) problems have increased. In indoor use, the wireless telecommunications environment can deteriorate due to multiplex reflection interference. This interference must be suppressed to improve wireless communications. Therefore, establishment of a multiplex reflection interference suppression technology is needed. In this study, a convenient, thin EM wave absorption wall was developed. The practicality of this wall was verified through the experimental results of a prototype absorption wall and the calculated results of a finite-difference time-domain (FDTD) numerical analysis. The proposed thin EM absorption wall and the verification results are described in this paper.","PeriodicalId":192851,"journal":{"name":"2009 20th International Zurich Symposium on Electromagnetic Compatibility","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127476516","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}
