Due to the laminated structure of the multilayer FPCB, however, an air gap could be introduced between the FPCB layers when it is bent, which deviates the designed characteristic impedance of the FPCB. For the prediction of the bent FPCB characteristics, a 3D electromagnetic model has been used, but the calculation time is too long, especially due to the meshed ground employed in FPCB. In this paper, we propose a circuit model which efficiently predicts the characteristic impedance of the bent FPCB with an air gap inside layers. The validity of the proposed model was verified between the EM simulation and measured results.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131314113","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}

From radioactive material projection in Japan to pictures of classified areas, known events have motivated the development of neutralization techniques. The use of high power directed energy weapons (DEW) is one of them. In order to estimate the efficiency of this solution, it is mandatory to have an in-depth analysis of the effects induced by radiofrequency DEW on targeted devices. Many studies related to the effects of electromagnetic interference on electronic devices have been released. A recently proposed approach has shown to provide insight on the propagation of hardware effects to the software level on tested targets using a health monitoring software. In this paper, we propose to design and run arbitrary software on a locked target to gain access to the internal sensors and logs available in the device. Relevant effects were obtained, opening the possibility to both neutralization and hardening strategies as well as estimating the protection efficiency provided by such solution.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123193876","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}

Interconnects can be studied by using the multiconductor transmission lines (MTLs) theory. Mathematical models of MTLs are normally validated with the aid of well-known software, such as MATLAB or PSpice. Simulink is part of the MATLAB suite but is not frequently used, and it is often underestimated both in academia and in the university education. In this paper, we briefly review the mathematical model for MTLs called DeRaG, which is a rational model based on delay extraction. Then, we propose the corresponding Simulink implementation for a 3-conductor transmission line. The Simulink has high readability, is accurate and the simulation time is remarkably faster than the corresponding model obtained in PSpice.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126234107","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 abovementioned parameters allow a broader characterization of the oscilloscope-based implementations of CISPR 16-1-1 measuring receivers, providing relevant specifications that are beyond the standardized baseline requirements. Such metrics are assessed using the actual settings and operating conditions required for compliant time-domain EMI measurements. For the specific oscilloscope used in the experiments, the noise figure is measured for all the different vertical ranges between 5 mV/div and 1 V/div. Likewise, the linearity and the dynamic range, in terms of the effective number of bits, was measured for sine wave input signals with an rms voltage swept between 20 mV and 1 V. This experiment was repeated for CISPR bands A, Band C/D using 10 kHz, 1 MHz, and 100 MHz sinusoids, respectively. The results allow a more comprehensive comparison between Full-TDEMI measurement systems and the more conventional superheterodyne architecture receivers that are completely specified in the frequency domain.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121497478","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 this kind of movement that enables the oscillating wall stirrer to implement, in a very easy and successful way, a hybrid stirring strategy combining source position stirring together with the normal tuner stirring. The performance of the hybrid strategy is compared to the traditional oscillating wall stirrer technique by means of several performance indicators. We further observe for this combined stirring, a significant increase in the working-to-total volume ratio with respect to the (already high) working-to-total volume ratio of the oscillating wall stirrer alone.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126079592","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}

Like any wireless technology, LTE is vulnerable to radiated electromagnetic interference. In this paper, we show how the levels from equipment fulfilling the standard EN 55022 can affect the performance of LTE. The impact is investigated on two control channels, the primary synchronization sequence in the downlink and a control channel for the physical layer in the uplink. Results show that the uplink control channel is more sensitive to interference and can be affected by equipment within hundreds of meters from the base station. The synchronization channel is more robust, but can be affected by equipment close to the mobile and then prevent the mobile from entering the network.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121122556","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}
