Our study integrates both 3-D full-wave simulations using the finite-difference-time-domain solver and experimental validation within the frequency range of 200 MHz–1 GHz. In the simulations, near-field sensors representing external antennas were utilized to assess the gasket's shielding performance at various angles and locations. Additionally, the simulations explored the variability in shielding effectiveness when employing both antennas. For the experimental set-up, only the impinging angle of 0<inline-formula><tex-math>$^{circ }$</tex-math></inline-formula> was considered to calculate the gasket's shielding effectiveness. The study demonstrates a good level of correlation between numerical simulations and experimental validation, revealing that tuned dipole and log-periodic antennas exhibit similar behaviors in terms of shielding effectiveness. Finally, the article emphasizes that despite the recommendation in the IEEE Std. 299 to use tuned dipole antennas, log-periodic antennas can be equivalently utilized due to their ease of use and practical perspective.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 2","pages":"598-608"},"PeriodicalIF":2.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143452052","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}

Therefore, it is necessary to study the failure mechanism of digital control circuits under mixed electromagnetic interference (EMI) and electromagnetic compatibility (EMC) design method to the failure problem. The digital circuit failure behaviors under mixed EMI of electrical fast transient (EFT) and surge are tested and analyzed. This article innovatively proposes an evaluation method of failure threshold of digital control circuits, that can be applied to the case where both voltage and current may change under mixed EMI of EFT and surge. The proposed evaluation method is dependent on the instantaneous product of amplitude and slope of the power supply port voltage of the regulator chip. The port voltage transfer characteristic of the regulator chip expressed using transfer function under mixed EMI is obtained. Then, the coupling model of mixed EMI of EFT and surge on the digital circuit board is built. The coupling model is validated by comparing the simulated results and measured results in 1000 V EFT and 20 V surge test. Based on the coupling model and the failure threshold, an evaluation method of circuit failure state under mixed EMI of EFT and surge is introduced and verified. Furthermore, an anti-interference filter design method is presented. Through a prototype experiment, the anti-interference filter design method is validated.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 2","pages":"467-476"},"PeriodicalIF":2.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143072401","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}

With the evolution of memory technology from DDR1 to DDR5, the requirements for higher transmission speeds and less signal distortion have necessitated more precise terminal designs. Simulations were conducted using ANSYS high-frequency structure simulator to assess the proposed stub design's high-frequency performance in terms of impedance, insertion loss (IL), return loss, and crosstalk (XT). Experimental results confirmed the superiority of the proposed design, which eliminates the 2.16 mm terminal stub from the conventional design. This modification minimized impedance variation, reduced IL by 0.2–0.4 dB in the 9–14.5 GHz frequency range, and enabled higher resonant frequencies in XT tests, thus enhancing signal integrity. These improvements hold significant promise for high-frequency applications, establishing a new design paradigm for DDR5 connector gold fingers and providing valuable insights for future high-speed memory interfaces.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 2","pages":"609-618"},"PeriodicalIF":2.0,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143054864","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 proposed method incorporates a compact electric arc resistance model rooted in the Rompe–Weizel law, calibrating by a physics informed neural network (PINN). The systematic uncertainties in the air discharge behavior due to environmental factors and measurement procedure are succinctly and effectively quantified through introducing an equivalent arc length in the compact model. A dedicated electrostatic air discharge behavior library is developed by a reduced-order partial element equivalent circuit model for training the neural network. The PINN calibrates the arc model according to the measured discharge currents on a standard ESD calibration set. The fidelity of the calibrated compact electric arc model is verified by the simulation and measurement. The efficacy of the proposed approach is observed through a case study.

Three structures are investigated: the shorter slotline compensation structure; the CSL mode filter structure; and the hybrid structure. The shorter slotline compensation structure places the double-ended open-circuited stubs underneath the shorter slotline of the coplanar waveguide to compensate for the phase difference between the shorter and longer slotlines of the coplanar waveguide. The resulting CSL mode conversion is as small as −15 dB from dc to 12.5 GHz. The CSL mode filter structure places the double-ended open-circuited stubs underneath both the shorter and longer slotlines of the coplanar waveguide to generate a resonant frequency for the CSL mode of the coplanar waveguide at 12.5 GHz. The resulting CSL mode conversion is as small as −15 dB from 12.5 GHz to 20 GHz.

This reduces the performance of the circuit. While much analysis has been performed on radiated emission in normal circuits, no study has been conducted on superconducting circuits, which are recognized as a new generation of electronic devices. In this article, the radiated emission from superconducting coplanar waveguide (SCPW) transmission lines is investigated. To this end, the current density distribution in the SCPW cross section is required. A procedure is presented in this article through which the current in the ground plane is related to that in the superconducting strip. This is based on the conformal mapping approach. Therefore, by using the current in the strip available in our recently published article, the current in the ground plane and subsequently the electromagnetic radiation from the SCPW can be obtained. The radiation from the SCPW is examined at different temperatures as well as different film thicknesses and different SCPW gaps. Results show that as the temperature increases, the SCPW radiates a lower amount of power. The same behavior is seen for decreasing the SCPW gap. Furthermore, our study reveals that the SCPW with a thinner film radiates a lower amount of power.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 3","pages":"949-955"},"PeriodicalIF":2.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020774","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 concentrated complex wire-conductor structure, such as PV panels, dc line of PV, grounding grids, and power distribution towers, are modeled using PEEC, while the long-distance transmission lines, such as buried cables and overhead lines are modeled with MTL. Both the ac side and dc side of the system are simulated synchronously, and the influence of the ac system on the dc system, including surge protecting device (SPD) installation, and grounding configurations are discussed. It is noted that a direct lightning strike on the dc side poses a significant threat to the system. However, when considering the connection to the ac system, the risk of lightning-caused overvoltage is mitigated. Moreover, this overvoltage reduces as the number of PV panels increases. For safe operation, it is essential to incorporate grounding at both ends of the cable enclosure and establish equipotential bonding among various grounding electrodes.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 2","pages":"658-666"},"PeriodicalIF":2.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142989027","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}
