Those two fundamental errors produce misclassified PT pass/fail results, which can have serious economic consequences for both EMC test laboratories and their customers. This article first reviews the published literature on quantitative EMC PT from the standpoint of assessing the statistical methodologies used and how the pass/fail criteria were applied. Next, this article discusses the effects of these statistical procedure errors. Finally, it details a practical, more accurate alternative Bayesian method that incorporates the maximum permissible error as the \u0000<italic>a priori</i>\u0000 information in its analysis model. This method treats the quantitative EMC PT data as a population with no specific presumed distribution.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"66 6","pages":"1780-1792"},"PeriodicalIF":2.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While data-driven deep learning exhibits robust capabilities for temporal transient modeling, it often ignores the correlations among high-speed links sharing similar structures, necessitating separate retraining for each distinct case. In this study, we propose a new transient modeling approach for high-speed links employing a transfer learning-enhanced deep simple recurrent unit (TL-DSRU) method. The deep simple recurrent unit architecture overcomes the challenges in handling sequential data and parallel processing found in traditional recurrent neural networks, enabling efficient modeling. Our technique leverages the initialization principles of transfer learning, utilizing a pretrained model of a basic high-speed link to enhance the comprehension of more intricate cases. The proposed TL-DSRU model combines parallelization and transfer learning initialization methods to balance training speed and accuracy, thereby enhancing the practicality and generalization potential of neural network-based transient simulation for high-speed links. Comparative experiments demonstrate that the transfer learning-based initialization method substantially outperforms typical neural network random initialization techniques, delivering markedly improved time-domain waveform prediction accuracy across various channels and equalization in high-speed links, as well as yielding more precise predictions of eye diagram parameters.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"66 6","pages":"2065-2073"},"PeriodicalIF":2.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integration of “LL” shaped defected patterns and trapezoidal tabs are specifically engineered to concurrently increase capacitive coupling and decrease inductive coupling, mitigating FEXT to a greater extent. The proposed methodology is comprehensively analyzed utilizing the generated equivalent circuit model. Moreover, the capacitance and inductance matrices of coupled line, tabbed routing, and the proposed structures are extracted from full wave simulations and analyzed with numerical equations to ensure an accurate evaluation of FEXT. To validate the efficacy of the proposed designs, the structure prototypes are implemented with FR-4 printed circuit board. The <italic>S</i>-parameters performance and eye diagrams are measured and compared. The measurement results demonstrate that the proposed structure effectively enhances FEXT behavior while ensuring robust high-speed signal propagation along the transmission paths. Specifically, FEXT is reduced by 15 dB within the frequency range of 1–18 GHz, and the maximum reduction of 55 dB at 10.6 GHz. The proposed structure exhibits superior FEXT behavior improvement within a wide frequency range, indicating significant potential for practical wideband high-speed applications.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 1","pages":"247-253"},"PeriodicalIF":2.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This CM-based resonance model, derived from the Poynting theorem, extends its application to accommodate reconfigurable frequency-selective surfaces (RFSSs) by integrating the equivalent circuit of diodes into the impedance matrix of the method of moments. The model not only provides a well-defined physical interpretation with the CMs but also enhances the analysis and design process of FSSs through insightful field perspectives. To illustrate the proposed CM-based resonance model, we exemplify band-stop and band-pass properties using two types of dipole structures, where the substructure impedance matrix transformation is used to account for the interelements coupling. The model is validated through comprehensive full-wave simulation results. Next, a single-layer triband RFSS is further designed with the aid of the formulated model. Prototypes are fabricated and subjected to measurements, revealing good agreement between simulations and experimental results. The confirmed usefulness in guiding the RFSS design of the proposed resonance model is expected to be of potential application in EMI shielding.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 1","pages":"117-127"},"PeriodicalIF":2.0,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
