We introduce a new, elliptically flattened design that could have elliptic cylinder, oblate or prolate spheroidal shapes. As a result, the absorbing core could now be flattened to a strip (elliptic cylinder) or a disk (oblate spheroid) and therefore match well-established planar fabrication techniques. First, we present a general and complete theoretical description that includes 3D oblique incidence, and then test the theory with ray-tracing and full-wave simulations of elliptic absorbers that confirm flawless performance at complete acceptance angles.","PeriodicalId":6587,"journal":{"name":"2016 10th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"12 1","pages":"175-177"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84191627","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}

Superspheres are solids with intermediate shape between a sphere and a cube, whose external boundaries are described by Lamè surface equation. Thanks to its particular shape, a core-shell supersphere resonates at a lower resonant frequency with respect to a conventional core-shell spherical nanoparticle with same electrical dimensions. Such a characteristic allows relaxing the fabrication constrains, i.e. extremely thin shells, typically required for making the conventional spherical core-shell nanoparticles to operate in the lowest region of the visible spectrum. Here, after having discussed the geometry and electrical response of a core-shell supersphere, we report some preliminary results on their successful employment in the implementation of three optical devices: a trasparent screen, a biosensor and a mantle cloak.","PeriodicalId":6587,"journal":{"name":"2016 10th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"108 1","pages":"298-300"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85122529","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}

One the of the intriguing examples is the so-called anapole moment proposed by Zel'dovich in connection with the radiation-less properties of a toroid solenoid. Furthermore, such electromagnetic configurations were recently suggested to classically describe the nature of dark matter. Recently, we demonstrated that one of the simplest allowing for direct observation of anapole mode in the visible is high-refractive index sub-wavelength nanoparticles. They provide new ways for excitation and investigation of the electro-magnetic properties of such nontrivial excitations.","PeriodicalId":6587,"journal":{"name":"2016 10th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"3 1","pages":"229-231"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90293456","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}

Making use of the duality principle, expressions for the behavior of the TE<sub>0</sub><sup>z</sup>-mode can be derived from the system matrices associated with the TE<sub>0</sub><sup>z</sup>-mode.
