The interdigital structure provides the impression of the negative-μ, and the double-spiral-defected resonant cell provides the impression of the negative-ε, so the proposed structure is composite right/left-handed structure. Then a miniaturized branch-line coupler using the proposed transmission line is designed. The designed coupler works at the left-handed bandwidth of the proposed composite right/left-handed transmission line, so it has a size reduction of 66% compared to the traditional branch-line coupler.","PeriodicalId":342849,"journal":{"name":"2019 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134549796","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}

Also, in this approach there is no need to incorporate probe correction unlike in the existing approaches. This is accomplished by solving for the equivalent magnetic current over a plane near the original antenna source and then employing the method of moments approach to solve for the equivalent currents. In this methodology there is no need to satisfy the Nyquist sampling criteria and a super resolution can be achieved in the solution of the equivalent magnetic current to predict the operation of the antenna. The two components of the equivalent currents can be solved independently from the two components of the measured electric fields. Sample numerical results are presented to illustrate the potential of a novel planar near field to far field transformation for the planar near field measurement technique.","PeriodicalId":342849,"journal":{"name":"2019 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121441575","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}

Different from the previous researches on coding metasurfaces in terms of phase distributions, we propose an ultrathin amplitude-modulated coding metasurface inserted with chip resistors at 5.76 GHz and 9.6 GHz. The proposed coding metasurfaces are composed of split-ring resonators (SRR) and inserted chip resistors with certain coding sequences for generating amplitude-modulated radiation patterns, while keeping other states unchanged.
