These devices can take the form of strip N-conductor structures with a various number of conducting layers, as well as cables. When designing them, during optimization, developers need to simultaneously consider several factors (e.g., the level of interference attenuation in a 50-<inline-formula> <tex-math>$Omega $ </tex-math></inline-formula> matched path with minimal mass and dimensional parameters) that the final product must satisfy. Additional complexity in the optimization of such structures is due to the variability of geometric and schematic models of them. Thus, the work details the main approaches to optimizing cable structures, including simultaneously several criteria. As global optimization algorithms, we consider a simple genetic algorithm, evolutionary strategies, and a random search method. The criteria include the amplitude criterion (minimization of the interference voltage at the structure’s output) and the matching criterion with the electrical path (minimization of reflections of useful high-frequency signals at the modal filter input). As the structures to be optimized, we take cable structures based on 3-conductor round and 2-conductor flat cables. This letter compares three algorithms, highlighting their advantages, disadvantages, peculiarities, and limitations in optimizing cable modal filters. Finally, we present practical recommendations for the use of optimization algorithms that are useful for designers of noise-suppressing cable devices.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"7 2","pages":"55-60"},"PeriodicalIF":0.9,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170864","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}

Therefore, it is crucial to define EMI-risk acceptability criteria (EMI-RAC) at the beginning of the electromagnetic-compatibility (EMC) risk management process to decide the acceptable risk levels to be achieved. However, defining these criteria is complex due to their dependence on various factors, such as regulations, standards, state-of-the-art (SOTA) practices, reference databases, and expert judgment. Therefore, this letter discusses how to distinguish acceptable, tolerable, and unacceptable risk boundaries and regions that define EMI-RAC. This letter provides practical guidelines for manufacturers through simple anecdotal examples where the business objectives are systematically transformed into technical acceptability criteria and eventually into verifiable EMC testing performance criteria. It also illustrates how manufacturers can represent criteria and balance risk reduction in medical device design to manage EMI risks. This is achieved in relation to risk-benefit analysis and SOTA solutions while avoiding field failures and damage to reputation.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"7 2","pages":"35-43"},"PeriodicalIF":0.9,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170866","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 design goal is to experimentally investigate reflection symmetric MLs and MF to analyze their characteristics and to comparatively evaluate their effectiveness in protecting electronic equipment from ultrawideband (UWB) interference. The intuition behind this letter lies in leveraging modal distortions to decompose UWB pulses into smaller, less harmful components. A meander routing scheme is employed to increase the differences in mode per-unit-length delays, thereby improving interference attenuation while maintaining a compact design. The novelty of this letter includes the first experimental analysis of time responses for one-turn and two-turn MLs, providing significant insights into their behavior and performance. Experimental results, corroborated by electrodynamic simulations, demonstrate that MLs achieve superior attenuation of UWB pulses compared to MFs of equivalent size. Specifically, meander routing enhances UWB interference suppression of the initial MF by at least 2 times in <inline-formula> <tex-math>${N} _{1}$ </tex-math></inline-formula>, 1.63 times in <inline-formula> <tex-math>${N} _{2}$ </tex-math></inline-formula>, and 1.36 times in <inline-formula> <tex-math>${N} _{5}$ </tex-math></inline-formula> norms. In addition, a novel postprocessing technique is introduced to identify combinational pulses in the time response of the one-turn ML, advancing the understanding of pulse decomposition mechanisms. This method successfully demonstrated the presence of combinational pulses. This letter represents a notable advancement electromagnetic compatibility (EMC) by offering efficient and compact solutions for safeguarding electronic systems against UWB interference.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"7 2","pages":"44-49"},"PeriodicalIF":0.9,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170974","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}
