The two formulations differ in the temporal mutual action between the time dependent quantities involved in the reciprocity process. Using an approximate expression for the dipole's current gives a convenient expression for the transfer response that can further be used for the analysis of the roles of different delayed wave-field contributions and causality.","PeriodicalId":400853,"journal":{"name":"2016 URSI International Symposium on Electromagnetic Theory (EMTS)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124508100","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 general understanding that increasing the number of shields of a cable will improve the shielding performance. However, there are situations in which a cable with multiple shields may perform similar to or in some cases worse than a cable with a single shield, and this analysis has seldom been discussed in the literature. We intend to shed more light onto this topic in this paper.","PeriodicalId":400853,"journal":{"name":"2016 URSI International Symposium on Electromagnetic Theory (EMTS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121307185","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 propose a research program based on careful reconsideration of how the concepts `information', `energy', and `system' can be fruitfully generalized beyond their original matrix of use within the traditional domain of time-dependent signal analysis. Based on recent theoretical advances in the areas of near-field dynamics and electromagnetic system-theoretic methods, we outline the new approach based on first developing an electromagnetic information theory, then using the concept of information buried within the spatial structure of the field to elaborate a calculus that can be systematically deployed in order to study and develop general electromagnetic systems simultaneously in both space and time.","PeriodicalId":400853,"journal":{"name":"2016 URSI International Symposium on Electromagnetic Theory (EMTS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133233330","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}

FSIW-based horn antennas are very promising in millimeter wave applications. To improve the bandwidth and efficiency of such antennas, a thick substrate is preferred but the microstrip feeding line becomes unacceptly wide to obtain a reasonable impedance. This paper introduces compact microstrip feeding lines with elevated ground plane for thick FSIW. Arbitrary characteristic impedance can be achieved without increasing the width of the feeding line, which will be very useful for the integration with other millimeter circuit components.","PeriodicalId":400853,"journal":{"name":"2016 URSI International Symposium on Electromagnetic Theory (EMTS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122373502","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}
