Widely used polarization diversity and defected ground structure (DGS) concepts are used for a 4-port antenna system to have improved isolation between individual antennas and hence better MIMO performance in addition to the unique harmonic suppression property.

It is also just a presumption of conformity with the Essential Requirements, as stated in the European Directive for EMC. There is a need for a robust and durable methodology that accounts for factors which are not covered by current EMC standards: the risk-based EMC approach. The term “risk-based EMC” along with the associated terminology is commonly interpreted differently by manufacturers, technicians, and users. This letter clarifies this often misused terminology. First, a comparison between the so-far implemented rule-based EMC approach and the up-and-coming risk-based EMC approach is made. Then, the application of risk-based EMC via a risk management-based methodology is proposed. The goal of this research is to provide an overview on the need of risk-based EMC, list the so-far used (or misused) terminology, and create a common platform of risk management-based methodology, which will act as a guidance tool for EMC engineers when it comes to clear and consistent communication and application of EMC engineering.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"7 1","pages":"5-13"},"PeriodicalIF":0.9,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10768197","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although GMMs have proven to be adequate for symbol detection at medium signal-to-interference ratios, the results of this study reveal a critical flaw in the conventional assumption that Gaussian models can accurately represent the received symbol distributions under all circumstances in harsh environments. This statistical approach proves to be inadequate at high levels of electromagnetic (EM) interference, resulting in an inability to accurately differentiate between symbols. The methodology is tested in a triple modular redundant system subjected to reverberant EM disturbances, with diverse PAM-4 as an encoding technique.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"7 1","pages":"14-18"},"PeriodicalIF":0.9,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489231","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 is mainly due to the need to simulate complex nonlinear electronic systems in computationally large environments. In this letter, we present a numerical procedure that accurately predicts conducted electromagnetic interference (EMI) in such systems. This procedure is based on the concurrent use of electronic-electromagnetic solvers linked by multiple source ports characterized in terms of S- and Y-parameters. Numerical results are validated, using a feature-selective validation (FSV) algorithm, when confronted with measurements taken at the input terminals of the line impedance stabilization network (LISN). Further representation of currents on the main board demonstrates the unique ability of full-wave simulations to provide their physical distribution, a result of interest not only for EMC purposes but also for further structural and thermal validations.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"6 4","pages":"160-165"},"PeriodicalIF":0.9,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142844486","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 patches have been included for certain dipoles to get a high and nearly stable gain in the entire operating frequency range. The fabricated PPLPMDA antenna is tested in terms of S-parameters, far-field radiation performance, IEMI sensing, etc., and witnessed good agreement between simulation and measurement results.
