The proposed approach numerically solves the 2-D electrostatic and magnetostatic Laplace problems in an inner region and represents the field in the outer region by a multipolar (MP) expansion whose coefficients are computed from the full numerical solution. This hybrid finite element method (FEM)–MP formulation decouples the in-cell parameters from the specific FDTD cell position and size, avoids repeated numerical computations when bundles cross many cells, and naturally accommodates dielectric insulation. The method is validated on three cases of increasing complexity: 1) a single insulated wire; 2) two bare wires; and 3) a realistic 31-conductor bundle. Results are compared against a pure FEM reference, a boundary element method implementation and Bérenger's center-based approximation. The proposed FEM(inner)+MP(outer) scheme matches the FEM reference with very small discrepancies. The study also shows that conductor interactions shift the effective expansion centers away from geometric centers and that electrostatic and magnetostatic centers differ in the presence of dielectrics, which are effects not captured by simplified previous analytic models.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"68 5","pages":"1226-1233"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11625738","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148595590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A parameterized two-dimensional finite-difference time-domain (FDTD) dataset is generated using a double-exponential E1 source over a structured design space defined by aperture width, aperture position, and effective polarization. A residual multilayer perceptron (ResMLP) learns the direct mapping from these parameters to the local probe waveform, peak electric field, total time-domain energy, and spectral band-energy ratio. Multitask learning jointly predicts waveforms and compact features, while waveform-to-feature consistency supervision ensures that scalar indicators remain physically aligned with the reconstructed transient response. Numerical results show that the model preserves dominant coupling trends and achieves high accuracy for both waveform and feature targets. Compared with repeated FDTD simulations, it reduces the average evaluation time from 20.25 s to 6.25 ms per sample, corresponding to a speedup of approximately 3,240×. The complete 2,800-sample dataset, including waveform reconstruction, is evaluated in 11.96 s, yielding an overall speedup of approximately 4,741×. The proposed method also outperforms polynomial ridge regression, RBF-kernel ridge regression, and nearest-neighbor interpolation in waveform accuracy while maintaining waveform–feature consistency. A controlled threedimensional extension incorporating cavity-depth and volume variations further confirms the transferability of the workflow beyond the two-dimensional benchmark. The framework therefore provides an efficient and physically meaningful tool for rapid screening, parametric sensitivity analysis, and early-stage electromagnetic compatibility assessment of aperture–cavity structures under transient excitation.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"68 5","pages":"1213-1225"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148755271","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 CW noise model represents a harmonic component of a clock signal that is unintentionally radiated from digital circuits based on electromagnetic noise measurement. The effects of CW noise on mobile communication systems are evaluated through wired and wireless measurements using multiple commercial user equipment. The results indicate that interference characteristics caused by CW noise strongly depend on the relationship between the CW noise frequency and channel mapping of the communication system. Severe degradation occurs when CW noise interferes with reference signals, while a slight impact is observed when it aligns with the center of channels that allocate only data bits. These trends were consistently observed across all tested equipment. This finding clarifies conditions under which CW noise used to represent a harmonic component of clock signal radiated from digital circuits, leads to strong interference and provides practical insights to set an emission limit and design high-reliability mobile communication systems.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"68 5","pages":"1085-1095"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11646566","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148728048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although deep learning methods show promise, their practical application is often hindered by substantial data requirements and limited generalization capabilities. This article proposes a data-efficient, multiobjective optimization framework to address these limitations. We employ a data augmentation strategy to significantly reduce the reliance on computationally intensive full-wave simulations. The model's data efficiency is verified through ablation studies, and its generalization robustness is rigorously validated using leave-one-group-out cross-validation. The resulting high-performance convolutional neural network is then integrated as a surrogate fitness function within an evolutionary multiobjective algorithm. This hybrid approach enables the efficient generation of a complete Pareto-optimal front in a single run, revealing the tradeoff between EMI suppression and via count. Furthermore, the analysis indicates that the optimization patterns revealed by the framework are consistent with underlying physical mechanisms, demonstrating clear physical insights. The proposed methodology offers an automated and robust pathway to achieving cost-effective electromagnetic compatibility in modern printed circuit board (PCB) designs.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"68 5","pages":"1234-1245"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148595592","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 EMS results reveal the susceptible frequency band from 70 to 100 MHz, with the critical threshold occurring around 90 MHz. This frequency-dependent behavior is explained by the combined effects of frequency-selective cable response associated with reflection and standing-wave enhancement, high-frequency parasitic coupling through the Ethernet isolation transformer, and the effective baseband response and filtering characteristics of the PHY receiver. The agreement between the explained resonance-related sensitive band and the measured minimum-threshold frequency supports the proposed EMS mechanism. Furthermore, a high-frequency equivalent model is developed to quantify port-to-port EMI transfer by incorporating transformer parasitic capacitance, inter-port capacitive crosstalk, and common-ground transfer impedance. The simulated transfer characteristics are validated by measurements, confirming that the model captures the dominant frequency-dependent inter-port coupling behavior. A comparative analysis of the EMS thresholds and port-to-port transfer characteristics provides frequency-domain evidence for identifying the dominant coupling paths in multiport Ethernet switches. The proposed mechanism-based analysis and validated model offer a reference for EMC assessment and robustness optimization of multiport Ethernet equipment.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"68 5","pages":"1096-1107"},"PeriodicalIF":2.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148860888","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}
