This article adopts a hybrid computational approach to analyze this issue, with an actual distribution line network modeled for a case study. The overvoltage waveforms and flashover pole counts under different lightning conditions, including the effects of LEMP, lightning strike points, lightning current characteristics, and the inhomogeneity of grounding resistance, are investigated. The results indicate that insulator overvoltage is highly sensitive to the LEMP effect, particularly when lightning strikes the poles. Increased pole density leads to greater overvoltage dispersion compared to sparse configurations. As the amplitude of the lightning current increases, the amplitude of the overvoltage on the insulator also increases, but the distribution of overvoltage remains essentially constant, which is significantly influenced by the complexity of the topology. The impact of uneven grounding conditions in distribution networks on overvoltage and flashover primarily depends on the grounding performance of the lightning-struck pole. The sensitivity of the LEMP effect to the lightning strike attachment point, the grounding resistance, and the line topology, as well as the comparison with that of the simple line configuration, were further summarized.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"68 4","pages":"951-961"},"PeriodicalIF":2.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148287929","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 enabling efficient energy transfer, the radiated magnetic field raise concerns related to electromagnetic field (EMF) exposure and electromagnetic interference, particularly with implantable medical devices. Existing mitigation approaches such as conductive shields, magnetic materials, and passive reactive loops are limited by tradeoffs involving efficiency loss, added mass, cost, or insufficient control. This article presents a comprehensive methodology for active magnetic field compensation, based on a machine learning-assisted optimization of the electrogeometrical configuration of an additional compensation (or shielding) coil, connected in series with the <italic>Tx</i> coil. The surrogate model guides the design to minimize leaked magnetic flux density in critical exposure zones while preserving power transfer efficiency above 90% under nominal load. Simulation results reveal that the proposed solution reduces peak flux density by up to 70% with a negligible efficiency penalty. The approach is validated through three-dimensional finite-element analysis and experimental prototypes.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"68 4","pages":"1025-1034"},"PeriodicalIF":2.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11475897","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148747980","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}

This article focuses on pulsed-CW excitation where a monochromatic CW signal is modulated by a rectangular pulse. This kind of excitation presents the advantages to expose the equipment under test to more realistic signals and broadening the effective excitation bandwidth around the carrier frequency. This study first aims to understand the physical phenomena involved in this narrowband excitation in a reverberant enclosure. The average envelope of the signal induced on the receiver (i.e., a receiving antenna) being decomposed in three different regions called “rise-time,” “steady-state,” and “fall time.” It is then shown that the a priori knowledge of the quality factor of the enclosure enables an accurate prediction of the average envelope of the received individual pulses in sufficiently well-stirred conditions. Finally, it is shown that a time-varying environment (i.e., a continuous stirring process) as the one obtained in a classical parallelepipedal RC continuously stirred or in a vibrating intrinsic RC (i.e., VIRC) allows a clear reduction of the overshoots observed on individual pulses during both transitions regions. Under these conditions, a high fidelity to the excitation signal can be achieved at the receiver, especially when the RC is loaded with absorbing material. The final objective of this article is therefore to contribute to demonstrate to the community of RC users that a pulsed-CW excitation in an RC can be well controlled and predictable, and thus capable of producing reproducible tests.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"68 4","pages":"825-834"},"PeriodicalIF":2.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148748484","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}

Assuming near-fields can be represented using a truncated plane-wave expansion, the CS approach estimates optimal solutions of coefficients in this expansion using considerably fewer samples than the theoretically defined Nyquist rate. The method is demonstrated in two phases: First, the simulation phase enables us to build and demonstrate the CS framework on a source model that mimics near fields from computing chips. Several simulation experiments are implemented to verify the compressibility of the dataset and the limits within which CS can be applied. Second, the measurement phase validates the methodology by implementing CS-based scans on a commercial test board and reconstructing the field maps expected from high-resolution scans. Experiments in the measurement phase also demonstrate the utility of the CS approach for anomaly detection using near-field measurements.

Immunity testing helps identify the frequencies at which these devices are more vulnerable, often termed weak spots. In biomedical instrumentation, where dependable operation is essential, such weak spots may still be excited by harsh and complex electromagnetic environments. One way to address this problem is to embed a frequency-selective detector that continuously monitors these weak spots and issues an early warning when potentially harmful disturbances occur. This article presents a proof-of-concept implementation in which a frequency-monitoring module based on a software-defined radio is integrated into a biosignals acquisition device. First, the weak spots of the acquisition device under test are identified using a “testing-to-failure” approach under controlled radiated immunity assessments. Next, a condition assessment framework for mission-critical systems is used to build a performance matrix that evaluates how reliably the integrated detector produces correct warnings and correct rejections when new electromagnetic disturbances are applied to the identified weak spots. The test signals are selected using a risk-based approach to represent worst-case scenarios for the detector. The evaluation on electrocardiograph signals reveals important tradeoffs in the hardware design and threshold configuration of the detector that should be considered when optimizing detection performance against electromagnetic disturbances. This work is distinguished by the integration of a frequency-selective detector into a biosignals acquisition device.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"68 4","pages":"813-824"},"PeriodicalIF":2.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148299413","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}
