In this paper, the Gerchberg—Saxton algorithm is used to retrieve the phase of the transverse magnetic near-field data measured on two parallel plates above the equipment under test (EUT). Then, the method of moments using roof-top basis functions is applied to reconstruct the horizontal electric current densities for the EUT. The proposed method is validated by comparing its results to full-wave simulations obtained using the CST-MWS software.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128458401","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}

It is traditionally measured by sampling the standing wave along a linear path at various quiet zone (QZ) locations per CISPR 16-1-4. The limitation due to data undersampling is well recognized. As the frequency range starts to extend to the millimeter wave band, the limitation becomes even more pronounced, to the point that it makes little sense to attempt to apply the same test methodology. A novel approach based on frequency domain mode filtering is presented here, which overcomes the difficulties in the traditional approach. In the proposed approach, an omni-directional transmit antenna is placed at the edge of the QZ, and a full rotation vector pattern cut is acquired. The data is then processed and decomposed into cylindrical modes, where a mode filtering algorithm is explored to separate the antenna response from the chamber reflections. The VSWR of the chamber can then be computed by comparing the filtered and unfiltered pattern. The mode filtering approach provides greater insights to the QZ performance, including showing the unperturbed antenna pattern, and the ripples caused by reflections separately. It is much less prone to undersampling because a dense angular step size can be easily accommodated using the existing turntables in EMC chambers.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130489190","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 introduced method allows engineers to calculate field coupling and crosstalk for multiconductor lines directly in circuit simulators without the need for field simulation programs. The presented model is suitable for EMC studies where the voltage response at the loads of the lines can be calculated due to plane wave coupling or due to lumped interference sources. The conductors are divided into cells and represented in terms of lumped elements and controlled sources. The presented model of multiconductor lines can be used in the frequency domain or in the time domain with nonlinear elements. The model validation shows excellent agreement of the results with those obtained with conventional field simulations.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132321337","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 advantages of RadioFrequency IDentification (RFID) systems have led to the development of Real-Time Locating Systems (RTLS) used for identifying, monitoring and tracking objects (e.g. tracking devices, things or people and even tracking patients, biological materials and pharmaceuticals in medical centers) increasing the quality and the efficiency of healthcare. In this study, a tracking system based on short-range radio frequency, UHF-RFID, is evaluated by measuring the electric field (E-field) emitted by an RFID DYANE Smartshelf (ETSI) at a frequency range of 865–868 MHz, and a methodology based on representing the measurements on 2D contour maps is proposed. Exposure levels due to the RFID localization system were analyzed in order to verify regulations concerning the safety of patients and workers in hospital environment, who often are exposed to the electromagnetic field (EMF) emitted there. Localized EMF exposure has been found at levels which may cause electromagnetic hazards in the specific health care environment, and potentially excessive exposure to EMF emitted by UHF-RFID devices may apply to patients or bystanders. The maximum E-field values obtained were no larger than $108.64/ text{dB}mumathrm{V}/mathrm{m}$, which meet 2020 ICNIRP recommendations and current Spanish regulation in this area, although it requires future wider studies.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134055641","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 literature review shows that several parameters compromise the inverter's performance using switching modulation techniques for non-linear loads. This paper presents a case study into four of them, namely dead-time, modulation index, modulating frequency and switching frequency. Yet, considering the standards requirements of harmonics control in VSDs, a second case study is also presented for a proposal of evaluating line inductors EMI filters by using the testbench. Therefore, the testbench can be used to improve EMI-based VSD performance and mitigate the conducted emissions by suppressing levels in the source and along the path, thus, ensuring improved electromagnetic compatibility in the system.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128953103","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}
