Power-line filters are one example of a mitigation technology that are overdue for improvement. Recent advances in filter characterization have been made as with the development of new test methods (i.e., IEEE 1560). Filters must also be able to withstand electrical disturbances in the common everyday electrical environment. Present equipment designs use traditional filters plus some type of surge protection device (SPD). Improvements to equipment and filter performance can be achieved by using a different approach to reduce emissions combined with integral surge protection. This paper not only discusses typical problems with filters but also presents a new technology for designing filters followed by some laboratory test data comparing traditional filter performance with that of the new filter technology.","PeriodicalId":440959,"journal":{"name":"2011 IEEE International Symposium on Electromagnetic Compatibility","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129069021","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}

However, the gain at a finite separation is no longer the same as that in the far-field region. In the present paper, a simple calibration method for E-field probes using dipole antenna factors (AF) is proposed. An E-field generated at a location is directly calibrated by using the AF of a dipole antenna. This method has considerable advantages in simplicity and compactness. In addition to analysis of the through performance of the method, uncertainty associated with this method is overviewed.","PeriodicalId":440959,"journal":{"name":"2011 IEEE International Symposium on Electromagnetic Compatibility","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121104637","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}

By optimizing the PCB routing, or enforcing a specific differential pin-out pattern, the crosstalk contribution from a different component or section of the link can cancel each other and result in a significant crosstalk reduction at the receiver. On the other hand, this paper also addresses another aspect of the crosstalk cancellation scheme: the crosstalk contribution from different link components may be un-intentionally cancelled out in full link simulation, and results in favorable but wrong simulation results. Suggestions on how to avoid this type of problem is given in the paper.","PeriodicalId":440959,"journal":{"name":"2011 IEEE International Symposium on Electromagnetic Compatibility","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121933128","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}

Using accumulated knowledge and experience, EMC-related committees have established guidelines on standardized acceptable values of EM radiation during device operation. Current electronic devices are usually designed so as to satisfy these EMC standards. However, the main aim of these standards is to reduce EM radiation that disturbs other devices, not radiation that leaks secret information. Even for EM radiation below the value specified in the guidelines, extraction of secret key information remains a possibility. In other words, unlike noise radiation in the field of EMC, there are no definite criteria regarding EM information leakage. Therefore, uncertainty remains as to whether conventional noise suppression techniques are applicable to the suppression of information leakage. This paper discusses the difference between using electromagnetic field suppression techniques for noise and for information by using a quantitative approach. Information leakage and effective countermeasures are investigated, based on a quantitative evaluation of the signal and noise components of the leakage.","PeriodicalId":440959,"journal":{"name":"2011 IEEE International Symposium on Electromagnetic Compatibility","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128159949","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 examination of the ray paths corresponding to erroneously predicted unstirred multipath components revealed that these ray paths intersect the reverberation chamber's mode-stirring paddles, absorber blocks, and various other objects in the chamber. This inspired a simple image-blocking model for the reverberation chamber's unstirred wireless channel, whereby contributions from ray paths intersecting the chamber's mode-stirring paddles and absorbers are neglected. This model elucidates the unstirred wireless channel's geometry-based multipath structure, justifies established best practices for reverberation chamber measurements, and enables the development of more effective techniques for mitigating the reverberation chamber's unstirred field components.","PeriodicalId":440959,"journal":{"name":"2011 IEEE International Symposium on Electromagnetic Compatibility","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131733034","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}
