While R-FSSs have been long used in the radar signature and electromagnetic interferences reduction, nevertheless the configuration where all the unit-cells are physically connected has not been yet thoroughly investigated for this aim. Indeed, the fishnet-like arrangement can guarantee extraordinary key advantages in terms of RAMs fabrication, especially for large production scales. Therefore, this article, by resorting to significant test-cases, aims at deriving practical design procedures to realize advantageous connections among adjacent FSS unit-cells. Specifically, the effects on the overall FSS impedance behavior of the geometrical variations in the unit-cell connections are deeply explored. To ensure the broad applicability of the presented guidelines, the study has been carried out by recurring to an equivalent circuit analysis, based on the transmission line theory, and on accurate full-wave simulations. To prove the practical significance of the developed guidelines, two prototypes of the same RAM based on a resistive and connected FSS have been fabricated. Both in a small flat panel and in a large-scale conformal arrangement, the electromagnetic reflection was drastically reduced in the band between 6 and 18 GHz, while significantly simplifying the fabrication process. In conclusion, the proposed research exhibits promising potential to enable an efficient large-scale fabrication for RAMs, by addressing the difficulties associated with the design of connected unit-cells.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 3","pages":"800-810"},"PeriodicalIF":2.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143946238","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}

Consequently, this article is structured to investigate the effect of the background distortions in the harmonic and SH ranges on the light flickers produced from low power LED lamps that are widely used in residential applications. Four scenarios are performed: The first and second scenarios are done by exposing the LED lamp to a background distortion with harmonic and interharmonic voltage components, respectively. The third and fourth scenarios explore the impact of the grid voltage distortion in the SH range with frequencies that are integer and noninteger multiples of the grid frequency, respectively, on LED lamp flickers. The conducted study comes to the conclusion that visible flicker only appears for scenario 2, in which the visible flicker effect is in inverse relationship with the interharmonic frequencies. In both scenarios 1 and 3, no visible flicker is detected. In scenario 4, the light flicker is negligible. The observations are carried out experimentally on a commercial LED lamp. Then a mathematical analysis is provided to explain the observations in the four scenarios. The main outcomes are validated through a simulation study.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 3","pages":"975-987"},"PeriodicalIF":2.0,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143915430","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}

Based on the principle of multi-frame average denoizing method, it makes use of the characteristics that the display depends on the periodic repetition of different video frames when displaying image information. Successive frames are superimposed to achieve image enhancement, which effectively reduces the influence of environmental noise. At the same time, the fusion of one-dimensional wavelet transform technology further improves the quality of image reconstruction. The experimental results show that, compared with the direct image reconstruction, the image signal-to-noise ratio, contrast ratio and acuteness of the fusion algorithm using wavelet analysis and frequency domain hierarchical image reconstruction are improved by 79.7%, 15.9%, and 47.8%, respectively.

By determining this statistical probability, product risk assessment, and the selection of appropriate ESD test levels can be performed to ensure the targeted field reliability is reached. Obtaining the necessary statistical information about ESD requires methods that can detect and quantify its parameters. Traditional ESD detection methods are predominantly stationary, requiring reference potential, and lack adaptability for portable devices and wearables. This article demonstrates a novel, portable in situ detection method based on on-body electric and magnetic field measurements. The proposed method integrates a wearable ESD sensor, capable of detecting discharge events, estimating voltage and current levels, and differentiating between human skin and human metal discharges. This sensor's design allows the characterization of the complex ESD environments of a person, offering a significant improvement over existing methods. Additionally, integration with a mobile application enables detailed analysis of the discharge scenario through user questionnaires for the first time.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 3","pages":"729-738"},"PeriodicalIF":2.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143569636","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 effectiveness of the proposed method is discussed in comparison with the standard test method from IEC 62333-2, particularly by examining the underlying mechanisms based on the image method. To establish a test setup for measuring intradecoupling at frequencies below 100 MHz, the effects of various factors including the distance between the two loop probes, the distance from the probes to the NSS, and the size of the NSS were investigated using three-dimensional full-wave numerical simulations and design of experiments. For validation, intradecoupling ratios of commercial NSSs were measured using both the IEC 62333-2 method and the proposed method with two rectangular loop probes. In addition, regression analysis based on the measurement results was used to derive linear equations for predicting the intradecoupling ratio based on the real relative permeability and thickness, within the frequency range where real permeability is constant. The intradecoupling ratios at 1 MHz predicted by these regression equations showed an average deviation of 0.36<inline-formula><tex-math>$%$</tex-math></inline-formula> from the measured values of real NSSs on conducting plates.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"67 2","pages":"384-391"},"PeriodicalIF":2.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143506803","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}
