The structure has a subwavelength thickness and is engineered to suppress all diffraction orders except for those of the desired orthogonal polarizations. This is achieved by using an asymmetric slot waveguide scatterer unit cell to ensure polarization-selective directional scattering. We first present the design rationale and demonstrate a PBS operating at ~ A = 752nm that reaches an efficiency of ~ 80% for both polarizations with a separation angle of ~ 80° between the polarized light beams. The structure has several advantages over typical grating or metasurface-based implementations, such as high efficiency at large separation angles, operation in any reflection-transmission mode (reflection only, transmission only, or both) and single periodic element requirement.","PeriodicalId":395568,"journal":{"name":"2019 Thirteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122406646","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 humidity sensitive conducting Pani - PTFE ring behaves like low loss conducting ring with wide-band magnetic resonance whereas the CRR does not show any resonant response as is expected. The results are analyzed using simulation studies for copper rings of similar dimensions. Magnetic resonance observed in Broad-side Coupled Split Ring Resonator (BCSRR) made of Pani - PTFE is also presented, highlighting its role in metamaterial based applications.

The advanced flux-gate technique is used. Magnetization of the fully saturated magnetic film is rotated in the film plane and the monitored magnetic field is measured by detecting variation of optical transmittance through the sensing element. The sensing element is a magnetoplasmonic crystal consisting of a gold grating with subwavelength period deposited on a thin transparent dielectric film of bismuth substituted iron-garnet. Geometrical parameters of the magnetoplasmonic crystals are adjusted to have pronounced resonances of the longitudinal magneto-photonic intensity effect (LMPIE). The experimental study revealed that such approach allows one to reach the 2nT sensitivity level which was limited by the noise of the laser. The demonstrated magnetoplasmonic magnetometry method is promising for mapping and visualization of ultra-small magnetic fields.","PeriodicalId":395568,"journal":{"name":"2019 Thirteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129311580","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}

Thus, in some sense gravitationally-coupled systems are similar to metamaterials, having high-Q resonant elements separated by much less than a wavelength, and supporting gravitational wave propagation through the resonant elements. These new results raise the question of whether the notions of gravitational Q and gravitationally-small elements may lead to insights for the development of gravitational meta-materials. Here, we review recent gravitational Q results, and explore potential inspiration from electromagnetic metamaterial frameworks where unit cells may be considered as electrically-small antennas. Finally, a gravitoelectromagnetic framework is used to explore a Veselago-inspired approach to hypothetical gravitational metamaterials, should a gravitational unit cell be found. In an astrophysics context, interstellar distances are also shown to be less than a gravitational wavelength for certain planetary orbits.","PeriodicalId":395568,"journal":{"name":"2019 Thirteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121170257","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 study surfaces that can enable nonreciprocal energy transfer between multiple Floquet channels. These surfaces are fully periodic arrays of nonreciprocal bianisotropic particles that can enable nonreciprocal wave manipulation with unitary efficiency. Notably, we study metagratings with bianisotropic moving particles as their building blocks. These bianisotropic particles are in fact stationary, however from electromagnetic point of view they emulate the characteristics of a real moving particles. As a possible application, we derive the required electric, magnetic, and electromagnetic polarizabilities of the bianisotropic moving particles for a metagrating capable of nonreciprocal space wave circulation with unitary efficiency.","PeriodicalId":395568,"journal":{"name":"2019 Thirteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126535502","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 RCA has a U-slot microstrip patch antenna (MPA) as the primary source. The cavity resonance is generated by the large ground plane and a single layer of partially reflective structure (PRS) as the superstrate, which is placed at a distance of a half-wavelength from the ground plane. The PRS consists of 12 × 12 square patch arrays. Integration with an FSS radome absorber is performed to create a high gain and low scattering functional antenna. The impact of this integration to the antenna performance is investigated. The input reflection coefficient, realized gain and radiation pattern are compared. They are relatively similar, without and with the FSS radome absorber. A slight increase in the realized gain is expected due to the contribution of the metallic FSS structure since the FSS structure is treated as the second PRS layer for the RCA in the integration.","PeriodicalId":395568,"journal":{"name":"2019 Thirteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130214310","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}
