Due to the high complexity and high aspect ratio of the inner structures of a printed circuit board (PCB), full wave modeling of a system including the external environment and enclosures is usually unrealistic. In this multi-step approach, the system is decomposed into internal and external domains by the PCB surfaces. The interior domain is first solved using the contour integral method to obtain equivalent surface currents, which serve as excitations for the method of moments to solve the external domain. Here, we focus on the radiation from the board edges by assuming solid plates on both upper and lower sides of the PCB. Various configurations will be analyzed to study the impact of exterior structures on the radiated emission of the system. The impact of the coupling from the scattered field back to the PCB will be discussed.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123724000","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 system consists in a network of Base Transceiver Stations (BTS) located on the track side and the trains are equipped with an antenna on the locomotive connected to an embedded mobile. The GSM-R antenna receives the signals sent by the BTS but can also receive in-band electromagnetic (EM) interferences present above the train. These interferences have therefore to be controlled to verify that their levels do not affect the quality of the GSM-R reception. This paper is focused on the research of observables and measurement methods efficient to control the EM disturbances produced on board the trains, in order to warrant the protection of the GSM-R communications.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131952677","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}

According to previous studies, the possibility of microwave-induced cataract formation has been experimentally investigated in rabbit and monkey eyes, while not for the human eye due to ethical reason. In the present study, we investigated the temperature elevation in the lens, the skin around the eye, and core temperature of numeric human and rabbit phantoms for plane-wave exposure at 2.45GHz. The temperature elevations in the human and rabbit phantoms were compared with the threshold temperatures inducing cataract, thermal pain in the skin, and reversible health effects such as heat exhaustion or heat stroke. The core temperature elevation is shown to be essential both in the human and rabbit phantoms as suggested in the international guidelines and standard.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129246214","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}

Good agreement is demonstrated. The optical electric field sensor has much higher sensitivity for SAR measurement than thermometers and the measurements are much quicker. The application of this technology allows the spatial distributions of SAR within phantoms during MRI to be measured.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128813882","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 conventional method of EMI forecast includes the resonance frequency and S parameter of single board itself. However, it was not enough to estimate the worst peak frequency of EMI accurately, because on-chip capacitance affects greatly on the resonance frequency. Therefore, the EMI forecast is required to be improved by including on-chip power distribution network (PDN) and package PDN too. In this paper, transfer impedance of the entire system was precisely analyzed. As a result, it was confirmed that the peak frequency of transfer impedance of total system showed better correlation with the measured peak frequency of EMI.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123325794","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}

By varying the model parameter A and Γ, interference from pure Gaussian to a highly impulsive interference can be represented. The digital communication system performance is often determined by using the well-known Gaussian approximation (GA) to determine the bit error probability (BEP) of the system. The GA-approximation has been shown to severely underestimate the BEP for impulsive interference and therefore an earlier proposal, based on a so-called Impulsiveness Correction Factor (ICF) is used to correct the GA-approximation. In earlier work, the ICF has been extended to the case in which the interference signal consists of multiple interference signals. However, a limiting factor in that case is that one of the interference signals has to be dominant in power. In this paper, a simple but useful method is proposed to derive the ICF for a sum of equally distributed Class A-interference signals when none of the signals are dominant in power. This method is a complement to the earlier method and extends the usefulness of the ICF in interference analyses to a wider area of interference signals.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"270 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116080584","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}
