Even the dispersion error under the coarse grid is very close to the dispersion error of the traditional central difference under the fine grid. And examples show that the high-order DSC-FDTD method is useful and valuable as a time-domain high-order method.","PeriodicalId":186847,"journal":{"name":"2022 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122053365","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}

These characteristics lead to a significant decrease in the performance of traditional EMR time series mod-els. To this end, a hybrid model based on wavelet decomposition (WD) and long-short time memory (LSTM) is proposed for the wideband electric field radiation prediction. The proposed model is verified by the measurement samples under different prediction steps.

However, the PDN impedance profile is never flat, so that the step response of the PDN can comprise components of multiple resonant frequencies with corresponding impedance peaks in the frequency domain. The superposition of resonant voltage waveforms excited by transitions of current load can result in worst-case scenario and then violates maximum specified voltage. A strategy of placing decoupling capacitor to flat the PDN impedance is proposed in this paper. The defined impedance deviation of the PDN impedance with the proposed method is 7.93 percent which is about two times better than 16.25 percent with commercial tools.","PeriodicalId":186847,"journal":{"name":"2022 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC)","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127398482","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 usual dielectric EBG structure is formed by embedding high permittivity rods with circular or square cross-section shape into the substrate of PCB. Several discontinuous band gaps can be obtained within a certain frequency range, while wide and continuous forbidden frequency band is preferred. In this paper, a method of expand the bandwidth of noise isolation using rectangular EBG units is provided. To simplify the problem under consideration, the center distance and dielectric constant of EBG unit is held constant, only the size of rectangular EBG unit is varied. In the first case, either the length or the width of the rectangular is changed. In the second case, both the length and width of the rectangular are varied, while its area is kept constant. The calculated results show that by adjusting the aspect ratio of the rectangular EBG unit, two adjacent band gaps can be merged together, therefore, the width of a single band gap can be expanded significantly, and the continuous bandwidth with noise isolation degree better than -35 dB reaches up to 5.7 GHz within 15 GHz.","PeriodicalId":186847,"journal":{"name":"2022 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116084922","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}
