The antennas are fed from the bottom plane with a WR-15 waveguide (V-band), which couples the wave to the RGW. CP is generated in a simple and effective way, by means of two orthogonal feeder arms that excite a CP in a diamond-shaped slot on top. A broadband matching with reflection coefficient magnitude below –10 dB (S$_{11} lt -$ 10 dB) is achieved from approximately 60.3 to 69.6 GHz $(gt 9$ GHz). Applying the axial ratio criterion (AR $lt 3$ dB) the bandwidth in CP is 14.48%, with respect to the central frequency (59 to 70 GHz). The maximum gain in both designs is obtained at 67 GHz, with a value of 5.49 and 11.12 dB respectively.","PeriodicalId":260995,"journal":{"name":"2020 Fourteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117063321","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}

Here, it is shown that, in the presence of third-order forces, in a periodic arrangement of an anharmonic mass-spring system, the rectangular bipolar pulse distribution, ansatz solution of the equation of motion, can be projected onto the exact solution. This latter is derived casting the equation of motion in the form of a cubic Duffing differential equation and describes the wave propagating inside the system. Simple expressions for the amplitude and the period of the rectangular distribution are derived from the matching of the first-order contributions of the two solutions. These results could be employed to further tailoring the properties of nonlinear seismic metamaterials for engineering applications.","PeriodicalId":260995,"journal":{"name":"2020 Fourteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132430483","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 show that the excitations of magnetic localized surface plasmons (MLSPs), surface waves hosted by a subwavelength negative magnetic permeability sphere, can yield a strong enhancement of the MRI scanner performances. In addition, we demonstrate that MLSPs can be mimicked by substituting the negative permeability metamaterial (MM) sphere with a homogeneous high-permittivity one of the same radius. Our approach overcomes several limits of the standard MM approaches (generally, based on effective medium theories) avoiding complex 3D fabrication procedures and removing the local spatial MM inhomogeneities whose presence is detrimental in subwavelength photonics applications.","PeriodicalId":260995,"journal":{"name":"2020 Fourteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125402441","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 known that the hybridization of recently emerged functional materials with conventional metasurfaces can lead to the implementation of dynamically tunable metasurfaces with real-time control over the wave-front of scattered light. Here, we propose several advanced dynamic platforms based on gate-tunable biasing and integration of indium-tin-oxide (ITO) and doped-semiconductors into all-dielectric/plasmonic nanostructures. Besides the widely-utilized gap-plasmon and Mie-type resonances to enhance the light-matter interaction, we focus on the excitation of guided-mode and Fabry-Pérot-type resonances with relatively higher quality-factors. This can potentially pave the way toward brand-new highly-efficient tunable reflective and transmissive optical metasurfaces in near-infrared (NIR) regime.","PeriodicalId":260995,"journal":{"name":"2020 Fourteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125296984","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}
