These electromagnetic interferences exhibit usually impulsive characteristics and it can seriously degrade the performance of the current wireless systems. Over the last few years, the Amplitude Probability Distribution (APD) had been formally written into CISPR16 as a measure of the emitted electromagnetic energy from electrical equipment. In this approach we present two APD measurement methods. The first method based on 12-bit A/D converter and the second one based on in-phase and quadrature components of the impulsive noise at frequencies between 20 and 3000 MHz. Electromagnetic interference measurements in three different industrial environments were performed using the developed methods with promising results.","PeriodicalId":268582,"journal":{"name":"2009 IEEE International Symposium on Electromagnetic Compatibility","volume":"161 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125942317","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}

An unshielded (lidless) version of the test chip is used, making it easier to identify emission sources. Preliminary results demonstrate that the propagation of EM waves into a circuit depends not only on the impedance profile of the power supply network, but also on different EMI protection strategies implemented into the IC.","PeriodicalId":268582,"journal":{"name":"2009 IEEE International Symposium on Electromagnetic Compatibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128398438","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}

Deriving samples of the desired observable from frequency-domain computations at uniform intervals may be prohibitively time consuming for highly resonant structures. This paper examines a technique for generating of wide-band data from Method-of-Moments (MoM) simulation by employing the Neville-type Stoer-Bulirsch inter-polation algorithm supported by adaptive frequency sampling of the observable. The key feature of the approach is its ability to perform interpolation over a wide frequency band with a single rational interpolant.

Powerlines, that often already exist to support energy distribution, can provide an economical broadband medium for high-speed reliable communication traffic, not only for equipment monitoring, protection, and control purposes, but especially today for supporting the smart home technology. However, despite several attractions, the low-voltage electrical network provides an unfriendly environment for data communications. Besides interferences, noise, attenuation, and multi-path reflections, the extremes as well as the unpredictability of the access impedance are limiting factors in the performance of PLCs. This paper presents a preliminary study about a possible methodology of designing an optimal broadband impedance matching circuit (BIM) for providing gain equalization and mitigation of the effects of low-impedance loads on the PLC modem in a wide frequency range. The design is achieved in successive steps by means of the Vector Fitting method, rational parametric approximation of the driving impedance and nonlinear optimization through a novel Meta Particle Swarm Optimization (MPSO).","PeriodicalId":268582,"journal":{"name":"2009 IEEE International Symposium on Electromagnetic Compatibility","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127300471","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}
