Many propagation models have been developed: some are curve-fitting models, some are based on the physics of the propagation path. Some models have been developed that incorporate the presence of vegetation and man-made structures (clutter) to more closely approximate measured data. However, no model thus far predicts path loss in all environments (urban, suburban, rural, forested, etc.). This paper introduces various propagation models and compares them to measured data. In the end, we present another predictive model that includes objects within the first Fresnel zone as a predictor for a more inclusive propagation model.","PeriodicalId":137753,"journal":{"name":"2019 IEEE International Symposium on Electromagnetic Compatibility, Signal & Power Integrity (EMC+SIPI)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124130942","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}

Contact resistance is considered since it is a non-negligible component in socket modeling. A Parallel Resonance Frequency (PRF) method is used to validate the EM model and verify the contact resistance. It is shown that a quasi-static solver can be used to extract S-parameter or RLGC parameters and construct an accurate equivalent model without port parasitic.","PeriodicalId":137753,"journal":{"name":"2019 IEEE International Symposium on Electromagnetic Compatibility, Signal & Power Integrity (EMC+SIPI)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126826957","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 assessment of the near-field zone is challenging because of the complex character of decoupled electric E and magnetic H fields [1]. A new generation of near-field vector probes provide a solution for high-resolution measurements of the complex electromagnetic field. The presented study evaluates impact of the H-probe on the tested field. In this study a 50$Omega$-terminated microstrip line (MSL) is used as a reference device for experimental and numerical analysis as a source of predominant E field; and experimental cross-talk of two probes, using a miniloop as a source of predominant H field, is assessed.","PeriodicalId":137753,"journal":{"name":"2019 IEEE International Symposium on Electromagnetic Compatibility, Signal & Power Integrity (EMC+SIPI)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122359036","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 analysis of the electric field distribution suggests two options for rod antenna placement and electrical operation. These two options are not presently considered by the standards but can produce resonance free response and measured levels compatible with current standard test setups. Experimental results are offered that confirm predictions and that are obtained in both semianechoic and fully-anechoic facilities.","PeriodicalId":137753,"journal":{"name":"2019 IEEE International Symposium on Electromagnetic Compatibility, Signal & Power Integrity (EMC+SIPI)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128104214","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}

{"title":"Specific Dependence on Absolute Humidity and Saturation Deficit of Air Discharge Currents from Electrostatic Discharge Generator with Different Approach Speeds","authors":"Takeshi Ishida, O. Fujiwara","doi":"10.1109/ISEMC.2019.8825310","DOIUrl":"https://doi.org/10.1109/ISEMC.2019.8825310","url":null,"abstract":"The International Electro-technical Commission (IEC) specifies air discharge immunity testing for electronic equipment in the standard 61000-4-2 under the climatic conditions of relative humidity from 30 to 60 % and ambient temperature from 15 to 35 degrees Celsius. For aiming to improve the testing reproducibility, to clarify effects of the above climate parameters on air discharge testing, we previously measured air discharge currents from an electrostatic discharge (ESD) generator with an approach speed of 80 mm/s under 6 combinations of relative humidity and temperature. The result showed that the same absolute humidity provides almost similar waveforms of the discharge currents despite different relative humidity and temperature. In this study, to further examine such combined effects, we measure air discharge currents from the ESD generator at a test voltage of 15 kV with three different approach speeds of 20 mm/s, 50 mm/s and 80 mm/s under 9 combinations of relative humidity and temperature inside and outside the IEC specified climate ranges. As a result, air discharge current behavior is affected by not only absolute humidity (AH) but also saturation deficit (SD) or the difference between the AH and the saturated water vapor amount. The humidity dependence differs according to the IEC specified and non-specified climate ranges, while it can well be explained by the SD. Under the IEC specified conditions, at faster approach speeds, the peak currents of air discharges have maximum values at AH7.70 g/m3 and SD15.36 g/m3, whereas they are 1.2 to 1.4 times larger compared to those at almost the same AH7.71 g/m3 and smaller SD5.14 g/m3, respectively. In the IEC non-specified climate range, however, regardless of the approach speeds, the current peaks noticeably reach maximum values at AH3.81 g/m3 and SD19.26 g/m3, which are 3.6 to 5.2 times larger than those at roughly the same AH3.96 g/m3 and larger SD35.64 g/m3, respectively.","PeriodicalId":137753,"journal":{"name":"2019 IEEE International Symposium on Electromagnetic Compatibility, Signal & Power Integrity (EMC+SIPI)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114694228","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}
