In this contribution the monitoring of the breathing activity of a man buried into a homogeneous lossy medium has been analyzed. The geometry of the scenario and the body have been simplified in order to model the electromagnetic problem of the interaction of the body and impinging field in a closed-form. In spite of the simple formulation the results are satisfactory and show how some a priori important system requirements can be obtained, as for example the most suitable working frequency range. The model is able to predict the sensitiveness in terms of phase and module variations depending on the scenario.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128507423","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}

As the frequency of functional and interference signals is increasing, we would like to characterise immunity for higher frequencies as well. In this paper, we show why typical IEC 62132-4 compliant DPI set-ups become inaccurate when going up to 20GHz. We propose to determine the power Ptrans actually transmitted to the device under test (DUT) by using offline short-open-load-thru (SOLT) or thru-reflect-line (TRL) calibration. Furthermore, we design a low-cost FR4 printed circuit board (PCB) that allows for testing of SOIC8-packaged ICs. We verify that this board has acceptable and reproducible losses up to 20 GHz, as well as acceptable crosstalk.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128571742","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}

Advantage of this technique compared to the nested reverberation set-up is that measurements can be conducted much faster and at much lower frequency.

The nonuniform multiconductor transmission line can be subdivided into sections of uniform MTL to compute the elementary ABCD matrices. This technique is used to calculate the transmitted power efficiency when the overhead wires have sag with ground wire. A comparison between uniform and nonuniform MTL is made to quantify the effect of the sag in the balanced differential mode. It appears that the effect of the sag is negligible for the power efficiency of the four-conductor transmission line working in balanced differential mode over a large frequency range. In this case, the ideal available span for PLC reaches 5000m.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127214850","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 algorithm, implemented in the frequency domain, consists of solving the integro-differential equation that relates the incident electric field with the current induced into the line. The unknown current is expressed by means of a Fourier series whose coefficients are calculated applying the Landweber method. The use of such method makes it possible to face both measurement and parametric uncertainties, since it has been developed and is widely used to solve inverse problems that are typically ill-posed.

In addition a set of high power EM threats are of even greater concern, although the probability of occurrence for each threat is low.
