At this stage, frequency response prediction techniques based on deep learning have been applied in the field of EMC, such as long short-term memory (LSTM). However, the current research is in the state of “one thing at a time,” and there is no systematic performance analysis or research on LSTM. In this letter, the performance analysis idea based on the feature-selective validation (FSV) method is proposed to comprehensively analyze the prediction performance of LSTM with the help of eight sets of classical electromagnetic data examples. Finally, the analytical conclusions obtained are applied to the prediction of the shielding effectiveness of metal boxes to verify the accuracy of the proposed analytical ideas.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"6 4","pages":"126-131"},"PeriodicalIF":0.9,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142844563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The idea of incorporating low-frequency resonators in the absorptive circuit is utilized for realizing a miniaturized broadband absorber. Further, the LC circuit resonator is studied and incorporated with the equivalent circuit model, leading to a transmission pole through the front resistive network. Correspondingly, a Minkowski fractal (MF)-shaped loop resonator is proposed on the top layer, which is capable of realizing a transmission pole in concurrence with the operating frequency of the bottom bandpass layer. The proposed FSR is a 2-layer design realizing high selectivity (\u0000<inline-formula> <tex-math>$Q{=}24.14$ </tex-math></inline-formula>\u0000) at the passband of 9.9 GHz, which makes it the most suitable candidate for shielding/radar cross section (RCS) reduction applications of the narrowband radiating systems. Moreover, the proposed rasorber also exhibits compact size (\u0000<inline-formula> <tex-math>$0.015{lambda }_{L}^{2}$ </tex-math></inline-formula>\u0000), less thickness (\u0000<inline-formula> <tex-math>$0.081{lambda }_{L}$ </tex-math></inline-formula>\u0000), and wider absorption bands (3.7–9.3 GHz and 10.6–15.9 GHz in the lower and upper bands, respectively), in comparison with the existing literature. Furthermore, in the proposed FSR, the passband can be varied from 9.2 to 12.3 GHz by tuning the parameters of resistive and bandpass layers.

The proposed method enables a sink device-only compliance test by effectively emulating the source devices and channels, which reduces the test time and cost. The effectiveness of the proposed link emulation method is demonstrated by comparing its performance with that of conventional compliance tests.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"6 3","pages":"102-105"},"PeriodicalIF":0.9,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142143818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first design combines two types of FSS slots based on the SIWC to display distinct characteristics in terms of their cavity designs and performance. The design consists of a Y-shaped slot in conjunction with an annular slot within a circular cavity. Consequently, the structure exhibits performance features of a sharp roll-off and dual band-stop response across 1.7–2.7 GHz and 4.6–5.6 GHz with a fractional bandwidth 45% and 20%, respectively. The second design comprises a slotted rectangular SIW cavity-based FSS which exhibits a wide band-reject response across 2.9–19.8 GHz with a fractional bandwidth of 149%. To validate the concept, tangible prototypes have been fabricated, and their functionality has been verified by measurements. The estimated and experimental results show a strong correlation.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"6 2","pages":"62-66"},"PeriodicalIF":0.0,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141164686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is known that nonlinear loads pose PQ problems in large grids, but this problem is even more prevalent in smaller grids.
