After considering several improvements to the original model of a CPW loaded with pairs of SRRs presented in 2003, such as mixed (electric and magnetic) coupling between the line and the rings, and the effects of coupling between resonators of adjacent cells (bandwidth enhancement through the presence of complex modes), the focus here is to analyze the effects of coupling between the SRRs forming the pair in each unit cell. Thus, a model that considers magnetic coupling between the line and the rings, as well as magnetic coupling between the pair of rings, is presented and analyzed. The model is validated through preliminary results inferred from full wave electromagnetic simulation.","PeriodicalId":151955,"journal":{"name":"2014 8th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131335805","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 filtering module, sandwiched between two thin dielectric slabs, consists of a annular aperture in a metallic screen which exhibits zero reflection, and thus maximum transmission, in a narrow frequency band around its resonant frequency. An artificial spatiotemporal modulation of the effective permittivity function around the annular aperture is introduced and, exploiting the concept of Angular Momentum-biased metamaterial, a non-reciprocity behavior takes place. The transmission and reflection coefficients turn out to be different for left- and right-handed circular polarized fields when impinging from the same side or, similarly, for the same polarization impinging from the opposite sides. Then, the non-reciprocal filtering module has been integrated in a circular waveguide and in an aperture antenna and we show some preliminary results of this new family of magnet-less non-reciprocal components.","PeriodicalId":151955,"journal":{"name":"2014 8th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120858108","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 find that array-induced Fano resonances have the potential to be narrower than isolated-cluster-induced ones, and may lead to even larger field enhancements. We provide two representative examples: (i) a metasurface made of circular nanoclusters; (ii) a metasurface made of linear trimers. However, in principle the concept here introduced can be empirically extended to any cluster size and configuration. Application of array-induced Fano resonances include the improvement of sensor devices, for example.","PeriodicalId":151955,"journal":{"name":"2014 8th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128916844","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}
