Owing to the use of a simple low-pass filter, this novel form of relations is much easier to implement and understand than previous approaches. In this paper, we demonstrate, through a rigorous theoretical analysis and numerical tests, that the novel method provides a better estimation of the detected violation. The proposed analysis also elucidates the effect of the low-pass filter on the causality test.","PeriodicalId":279929,"journal":{"name":"2014 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117248724","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}

Because high power energy is transferred via air, however, the problem of electromagnetic radiated emission from WPT systems is expected to be serious. In this paper, an electromagnetic interface (EMI) and radiation from WPT systems are discussed. Three example technologies for suppressing the electromagnetic-field (EMF) noise and EMI noise from WPT systems are presented. EMF noise from different receiving (RX) coil topologies is characterized and an EMF noise suppression technology using a ferromagnetic material and metallic shielding is analyzed. A handheld resonant magnetic coupling charger (HH-RMCC), a WPT system with very low EMI noise, is then introduced. The proposed technologies for suppressing EMF and EMI noise from a WPT system will be helpful to design engineers.","PeriodicalId":279929,"journal":{"name":"2014 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126067782","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}

A statistical model (the Random Coupling Model) for describing the coupling in and out of irregular cavities is used to study the field fluctuations in interconnected environments. It is imagined that the coupling between environments is established by apertures. Monte Carlo simulations are presented for the transfer function between terminals operating in two- and three-cavity chains. The theory confirms numerical and experimental observations of other investigators on nested reverberation chambers. In particular, it is argued that linear chains of N interconnected enclosures can emulate a N-Rayleigh scattering process. Results are of interest for creating laboratory fading channels beyond isolated electromagnetic environments.","PeriodicalId":279929,"journal":{"name":"2014 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"136 4 Pt 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123693310","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}

We provide a broad overview of the hardware/software co-design space for an essential component of many cryptographic protocols. Based on our experience from teaching a master level course about hardware/software co-design, we explore four typical implementation options and provide concrete implementation results. In addition to the aforementioned criteria, resistance against implementation attacks is vital for the security of embedded cryptographic devices. We analyze our four implementations with respect to a security issue that is due to their electromagnetic emanations, and highlight multiple vulnerabilities that can be exploited to break their security. Next, we investigate state-of-the-art implementation options that are supposed to resist these attacks. We detail their implementation cost and show that it is non-trivial to implement these options securely. Our main contribution is a comprehensive analysis of many implementation options with respect to implementation cost and attack resistance on a single common platform.","PeriodicalId":279929,"journal":{"name":"2014 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126707460","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}

This paper deals with a specific question about the size of the power area fill used to route the power current from the dc regulator to integrated circuit(IC), and also used for connecting to the decoupling capacitors. With increased PCB real estate costs, narrow power fills are required, which results in an increase in the connection inductance of decoupling capacitors. This paper uses a proven lumped circuit model extraction procedure, based on the first principle resonant cavity model, to demonstrate the effect of narrow and wide area fills used in typical PCB PDN designs. The frequency domain results thus obtained are used with typical IC current draw profiles to show the impact on the noise voltage developed at the IC. Some design guidelines and conclusions are drawn from these results.","PeriodicalId":279929,"journal":{"name":"2014 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123676101","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}

Jitter-to-amplitude-modulation transfer functions are derived for sinusoidal jitter and random jitter in terms of the signal transfer function or S-parameters. Input jitter is shown to induce amplitude modulation in the output signal as a result of channel dispersion, leading to voltage noise at the channel output. RJ induced voltage noise is found to scale uniquely with channel loss. To verify the theory, numerical simulations are performed on channels with different losses and at various data rates. The input clock signal is represented with a square wave, and the output signal is calculated by linear superposition of the channel step response. Theoretical and simulation results are found to be in excellent agreement.","PeriodicalId":279929,"journal":{"name":"2014 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116354277","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}
