These vehicles, at times, integrate major electrical components into the vehicle structure placing these components near vehicle occupants. With this practice, there is the concern of exposing occupants to the magnetic field generated by these nearby electrical components due to the high current. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) established guidelines for general public exposure to electric and magnetic fields which offers guidance on potential health effects when humans are exposed to Non-Ionizing Radiation. In this paper, the application of these guidelines in an automotive setting will be discussed along with some of the challenges involved with applying this guidance. Some conditions at the basis of the ICNIRP guidelines do not align with the automotive environment, such as close proximity of current-carrying wires resulting in localized fields and maximum coupling to the exposed individual. This, along with some of the conservative assumptions made in the establishment of the Reference Levels, can pose a challenge when attempting to define magnetic field emission limits inside the vehicle.","PeriodicalId":120342,"journal":{"name":"2018 IEEE Symposium on Electromagnetic Compatibility, Signal Integrity and Power Integrity (EMC, SI & PI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115183199","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 paper proposes a novel method to evaluate the MRI RF induced heating effects of circular external fixation devices utilizing an innovative leg phantom. A number of essential geometrical parameters, i.e. number of screws and wires, ring frame diameter, strut length, and insertion angle were numerically investigated to study the RF induced heating mechanism and behaviors of circular external fixation devices. Numerical results suggest that non-wire configuration with fewer screws, large ring frame size, relatively large strut length and the maximum insertion angle pointing outwards may lead to the worst case MRI RF coil induced heating. The peak spatial average specific absorption rate (SAR) over 1 gram can approach 341.3 W/kg with a 2 W/kg whole body SAR.","PeriodicalId":120342,"journal":{"name":"2018 IEEE Symposium on Electromagnetic Compatibility, Signal Integrity and Power Integrity (EMC, SI & PI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124272098","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}

Previous research has proved that the contents of an enclosure may greatly change the internal field and thus the shielding effectiveness. The power balance method is an efficient approach to analyze shielding problems of populated enclosures. One assumption of the power balance method is that in the steady state, the electromagnetic field in an enclosure is homogeneous. In actual circumstances, however, the presence of losses in an enclosure often compromises the field homogeneity and the power balance method may become inaccurate. A diffusion equation approach has been previously proposed to overcome this problem. In this paper, we predict the internal electromagnetic field of a populated enclosure by using the diffusion model, and compare them with the fields obtained by the power balance method, a fullwave electromagnetic solver and measurements, to demonstrate its efficacy. Comparisons between the diffusion model and the power balance method show that for populated enclosures, the internal electromagnetic field varies with position and that the diffusion model allows this to be observed.","PeriodicalId":120342,"journal":{"name":"2018 IEEE Symposium on Electromagnetic Compatibility, Signal Integrity and Power Integrity (EMC, SI & PI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125323342","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}
