The derivation of this model is more rigorous than previous derivations and models, but is still, admittedly, overly simplistic. However, this model should be applicable for a special class of antennas (those that can be modeled as an unknown 2-port network between the test port and an ideal antenna). For more realistic antennas, these models should still provide valuable insight into the possible behavior of any antenna. Using these models, we show that some previous assumptions regarding receiving characteristics (mismatch and efficiency) of an antenna are invalid: most significantly we show that there can be differences between the transmitting and receiving efficiency of an antenna, and also between the transmitting and receiving mismatch factors. However, we show that the errors are unimportant for most measurements. We also give justification for the assumption that the average reflection coefficient of an antenna in a reverberation chamber is simply the free-space reflection coefficient of the antenna.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132791509","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}

In this contribution, we quantify the effects of RPD on both planar and vertical interconnects. For planar interconnects, we focus on the impact of slits on reference planes of embedded microstrip lines in thin-film re-distribution layers, considering the lossy nature of silicon. For vertical interconnects, we propose a circuit model that accurately captures the impact of RPD which occurs when signal vias transit power-ground plane pairs. This model can be used in the pre-layout stage to develop design guidelines to minimize the impact of RPD for Gb/s applications.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134452868","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}

In particular, an expert system pre-processor is used to set up the initial problem and assure the availability of a valid geometry model which is used to compute geodesic losses in the frequency domain. A knowledge base is constructed to contain essential modeling rules and “scripts” describing the steps involved in a validated, bottoms-up/top-down EMC analysis methodology. Problem reasoning is first performed on the system geometry in the pre-processing stage. An expert system based post-processor is then used to “monitor” the signal environment in the time domain and select the interference rejection scheme(s) appropriate for mitigating the effects of interferers present at a victim receptor port. Various interference rejection schemes are considered based on the interferer type and signal environment characteristics. This is necessary since a single interference rejection scheme cannot realistically be expected to suppress all types of interference that may be present.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114245383","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}

They may also be applied to H and E fields resulting from the spreading of distribution lines within a secondary power-distribution system down inside a manhole.

The quarter-wavelength resonator can provide a shorting path for return current around the resonance frequency of the stubs, which avoids common-mode noise to become the excitation source of the slot. To validate this idea, a test sample with using the proposed technique and a reference board without the solution are fabricated. The experimental and numerical results show the radiated energy due to the common-mode noise can be significantly reduced in broadband frequencies by using the propose resonators. The magnitude of common-mode EMI at 3 meter can be suppressed more than 5 dB at the frequency range from 2.1 GHz to 3.5 GHz, and even 10 dB during the frequency range of 2.4 GHz to 3.25 GHz.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125282140","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}

When carrying out EMI measurements, the antenna factor is an important and well-known characteristic. Generally, absolute calibration methods are commonly used for monopole antenna calibrations. However, establishing and keeping the traceability to standard quantities in absolute calibration methods are time consuming. In this paper, a new reference antenna method for non-resonant electrically short monopole antennas is proposed and investigated through a numerical simulation. Since the target frequency band is less than 30 MHz, the monopole antennas work as electrically short monopole antennas. The measurements are performed under the near-field condition. The results show that the proposed reference antenna method is available and effective in obtaining the antenna factor of a non-resonant electrically short monopole antenna.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121633297","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 problem is handled numerically by applying the Array Scanning Method that reduces the problem of an aperiodic source close to a periodic screen to a superposition of phased-dipole-array problems (where the array periods are the spatial periods of the shield). As a result, the Floquet theory can be applied and the scattering problem is solved in the unit cell by means of a periodic space-domain Method of Moment, which employs the Ewald transformation to compute the involved Green's functions with accelerated performance.
