The acoustic plane wave reflection from such an elastic-framed metaporous layer glued against rigid backing is studied. The analysis is performed by applying the multiple scattering theory in a dissipative Biot continuum while accounting for the fields scattered by the inclusion at the layer plane boundaries. It is shown that high broadband absorption of sound is achieved through the coupling of resonances of both the array and the shells with visco-thermal and elastic losses in the poro-elastic matrix. Moreover, the excitation of flexural resonances of the shells enable high-quality absorption of sound in the deep subwavelength regime. The semi-analytical approach of these multi-physical phenomena underlines the complex interactions between the scatterers and the poroelastic matrix, and allows the efficient computation of the fields.","PeriodicalId":6587,"journal":{"name":"2016 10th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"112 1","pages":"322-324"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90306541","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}

Typically confined to optical frequencies, it has recently been extended to microwaves but limited to the generation of an electromagnetic field with orbital angular momentum. In this contribution, we extend the possibility of generating structured fields at microwave frequencies to the case of an electromagnetic field with a Möbius strip polarization state. In particular, by using the cavity model, we analytically show that the required phase and amplitude patterns can be obtained by superimposing the radiated fields generated by different modes of a patch antenna.","PeriodicalId":6587,"journal":{"name":"2016 10th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"1 1","pages":"49-51"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75362995","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, we review the main characteristics of a conventional Doppler cloak, consisting of a system composed of a planar reflector covered by a spatio-temporally modulated slab. We demonstrate that such a scheme presents some drawbacks in terms of efficiency and, therefore, an enhanced version based on a momentum-biased parallel-plate medium is presented and discussed.","PeriodicalId":6587,"journal":{"name":"2016 10th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"56 1","pages":"295-297"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84905222","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}
