Therefore, potential harmful electromagnetic interference sources cannot always be identified and overcome. For detection of such threats, deeper investigation towards actual environments and existing cases is necessary. Risk-based EMC analysis can help distinguish critical cases in a common real electromagnetic environment as it deviates from the fixed standardized conditions. In this paper, a real case of a scooter, acting as a victim is represented via a simple model and macro-scaled parameters to identify and determine significant induced values caused by a coupling of an unknown source. Experiments as well as simulations validate the macro-parameter concept of the applied case and allow to perform a simplified study of its behavior when exposed to a complex electromagnetic environment without the necessity to run expensive and lengthy measurements. Even though the expected precision of such a test is expected to be relatively low, it is sufficient to be incorporated in the macro-parameter-based model focused on rough-but-usable EMI estimations within a complex environment rather than exact-but-wrong solutions obtained in a perfectly clean laboratory setup.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"358 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":"133632358","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}

In this research, we assume that the automotive wire harness is a bundle of wires above a conductor plane, and its behavior can be represented by stochastic transmission line equations. First, the proposed method constructs the regression models related to per-unit-length (p.u.l.) parameters by means of a machine learning technique. Then, the stochastic transmission line equations including the regression models are approximated using orthonormal polynomials through a PC formulation. Since the regression models correlate the geometric and shape parameters of the wires and the p.u.l. parameters, PC expansion coefficients can efficiently be calculated. We adopt three types of regression models and compare them to investigate the performance of the proposed method.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"33 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":"132566225","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}

In the presence of high intensity radiated fields, the cavity must be appropriately shielded to protect those sensors, this protection being detrimental to EM sensors sensitivity in their absence. We propose here an automatic and quasiinstantaneous activation of an electromagnetic shield printed on the window glass through the detection of the impinging electromagnetic field. The presented solution is based on thin micrometric mesh-metal film deposited on a glass substrate surrounded by a parallel arrangement of p-i-n diodes polarized by the EM field source itself. An experimental validation is performed using a reverberation chamber to generate the electromagnetic field stress while performing a shielding effectiveness measurement using the nested reverberation chamber test setup.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"62 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":"127067322","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}

One of the most challenging specifications is related to the spurious and its influence in other parameters such as linearity, noise figure, voltage spikes, S/I, etc. Concerning to carrier related spurious, the biasing networks usually have decoupling elements to mitigate noise effects. Nevertheless, if any noise source is not detected and considered in the design, the noise level could overcome the system specification, degrading its performance. The contribution in this paper is to stablish an easy prediction method, through the use of well-known characteristics of analog modulations (AM) and usual RF/DC figures, to estimate the carrier related spurious when a noise source from the biasing network is coupled into the RF system. To demonstrate the validity of the prediction method, a set of tests over different RF components is accomplished, as well as some measurements over a Multi-Chip Module (MCM), once the model has been extrapolated to complex systems.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"8 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":"129780266","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}

However, these methods require the exchange of information and simulation results for each time iteration. Moreover, the systems to be studied often introduce uncertainties related to their input parameters. Therefore, uncertainty propagation plays an essential role in electromagnetic compatibility design, and its impact should be highly considered. To tackle these constraints, this paper proposes an asynchronous temporal co-simulation method able to deal efficiently with uncertainties. The purpose is to obtain the stochastic response of the global system after dividing it. This paper details the basics of the technique illustrated, first, with two applications that highlight the method's efficiency. Then, the focus is put on the uncertainty propagation within sub-systems. The results obtained are compared with the global simulation and validate the methodology.","PeriodicalId":268262,"journal":{"name":"2022 International Symposium on Electromagnetic Compatibility – EMC Europe","volume":"560 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":"116649782","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 work researches the power-angle-frequency spectrum and the power-angle-delay spectrum of the directional antenna under test (AUT) in the loaded RC. Through the derivation and measurement, it can be verified that, compared with the angular spectrum under a single scanning radius, synthetic aperture angular spectrum under multiple groups of different radii can more clearly reveal the relationship between the received power of directional AUT and the changes of azimuth angles and time delays, reflecting the spatial and temporal characteristics of the channel in the chamber.

One of the crucial points of their design concerns the routing of the switching cells, which is critical with respect to Electromagnetic Compatibility (EMC) and surge voltages, thus requiring a preliminary investigation. For this purpose, a routing model using the Ansys Q3D software is studied in this paper. The data from the Q3D simulation are compared to the experimental results for the prediction of the EMC performance of the DC-DC full-bridge converter.
