The interconnection of different electronic systems through cables is becoming more difficult due to the hard restrictions related to EMC compliance requirements. Thereby, the research of new solutions able to provide a great attenuation ratio in a wide frequency band is a challenge. This contribution focuses on analyzing and comparing the performance of a novel sleeve ferrite solution based on a nanocrystalline (NC) structure with several materials with different compositions. This component is able to provide a high initial permeability value at the same time that maintains it up to some tens of megahertz. In terms of dimensions, NC suppressors can provide the same effectiveness than other materials with more reduced dimensions. The analysis of the impedance dependence of a sleeve ferrite core with its dimensions has been carried out. Five ceramic materials with different initial permeabilities from 380 up to 5000 has been compared with the NC core through representing their impedance traces. The results presented shows that NC provides the higher impedance throughout the frequency range of 1-500 MHz when it is compared with ceramic cores with the same dimensions.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"27 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129110146","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}

This material would allow getting similar results to a real material according to criteria as transient peak level, rise time, and half time duration. The study is limited to signals of frequencies below 1 GHz. Equivalent materials used are homogeneous with scalar characteristics (εr, σ), which are deduced from experiments led on real materials. The advantage of using these equivalent materials for modelling is to coarser mesh large cases in order to save computational resources. The first experimental part of the study is realized using the NADIA open strip-line, which is made of a horizontal metallic ground plane and the strip-line, terminated with resistors. A cinder blocks wall is built according to dimensions of NADIA window, and the strip-line is set up in front of the wall. With multiple electric field sensors, the attenuation brought by the cinder blocks wall is measured, but also the propagation time of the wave through the cinder blocks. The second part is focused on the modelling aspect. It permits to show if a simple homogeneous equivalent wall is able to model a numeric cinder blocks wall. It is also necessary to take care about the fact that the material is dispersive, and it is a matter to know if a simple couple (εr, σ) is sufficient to describe the material. Eventually, a simple method of building material characterization will be highlighted.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127944901","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}

They must be verified with Vector Network Analyzers (VNAs), which unfortunately have coaxial ports. These devices can be connected to the VNA only if they are embedded in adapters. In the verification process, the DUT must be de-embedded, i.e. the contribution of adapters must be extracted from the measured S-parameters. The Thru-Reflect-Line TRL calibration of the VNA is a suitable tool for that task, provided the necessary hardware and software facilities of the VNAs are available. If not, alternatives are required. The Authors presented such an alternative calibration method in their previous publications. Frequency limitations of the de-embedding process were reported in them. The reason is an abrupt transition from 50 ohms characteristic impedance of the coaxial structure by the cable connector to the 207 ohms characteristic impedance of the cylindrical rod wire above the reference ground plane. In this paper, the Authors present a newly developed adapter, with smoothly increased characteristic impedance, for which noticeable improvements can be observed.","PeriodicalId":225005,"journal":{"name":"2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121437233","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}
