The solution consists of embedding a periodic patterned surface between two dielectric layers and two metal planes. The novelty stems from the shape of the metal motif of the patterned surface of the unit cell. In each unit cell nine vias connect the metal patch to the ground; other four posts are posed on the metal patch in order to slow down the electromagnetic waves. The filtering properties of the device are assessed by numerically calculating the dispersion diagrams. Starting from small dimensions (2.5 mm), the device has been sequentially up-scaled until its selective properties met the requirements of the application, i.e. reduction of noise up to 6 GHz. Limits of the electromagnetic band-gaps are reported for various scales.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"41 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":"132862147","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}

Sufficiently large dielectric loss tangent was also observed in radio frequency range from 1MHz to 2GHz. The effect of density on the EM response properties in microwaves has been studied and found to correlate well with the electrical conductivity. In particular, the contribution to EM attenuation of absorption / reflection mechanisms was found to be very dependent on the cellular microstructure and changed from the ratio 2/1 for dilute samples (bulk density 0.042 g/cm3) to 3/8 for compact ones (0.150 g/cm3). The maximal 23 dB SE has been obtained in Ka-band for the samples with the highest densities, indicating that the carbon foam being extremely lightweight and characterized by relatively high electrical conductivity can be used as effective multifunctional EM coating.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"27 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":"121058371","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}

Also since a few years the PLC uses the distribution network to transmit data (Internet, television cable, house automation ...) among customers. In this work we are interested in calculation of the electromagnetic field emitted by the PLC network taking into account the power transformer. To realize this work we use the concept of Schelkunoff allowing to calculate the electromagnetic field emitted by an antenna located in a free space traversed by a current in the presence of the propagation. To validate our work we confront our calculation results with those obtained by the NEC-4 software which uses the antennas theory then, we propose some applications.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"15 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":"123609979","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 shown that high frequency oscillations with slew rates comparable or higher than the ones generated by the used semiconductors leads to significant higher noise emission in the radio frequency range. During turn on of the IGBT a high frequency oscillation is created between the stray inductances of the DC-Link and the reverse capacitances of the blocking freewheeling diodes. The DC-Link stray inductances are charged by the reverse recovery current of the freewheeling diode. When the reverse recovery current peak is passed the diode begins to block and the energy stored in the inductances oscillates to the reverse capacitance of the diode. The quality of the oscillation is mainly influenced by the tailing of the diodes reverse recovery current. At the investigated three phase, 600V, 200A power module the observed turn on resonance frequency is 33MHz. The crucial characteristic of this phenomenon is that the noise emission is not only higher at the resonance but for all frequency above, too. By reducing the module inductances the resonances are shifted to higher frequencies but measurements show that the emitted spectrum stays the same. To reduce the module inductances do not solve the problem. The results of the investigation enable the design of power modules with reduced radiated emissions.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"43 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":"124013682","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}
