However, realizing them with practical metallic patterns has posed challenges. In this paper, we propose a rigorous approach for designing cylindrical metasurfaces that are realizable. A multimodal wave matrix formulation, which accurately describes intercell coupling and accounts for spatial dispersion, is reported. Additionally, a cylindrical extraction technique is adopted to account for the curvature of metasurfaces. As a proof of concept, a practical, coaxially-fed azimuthal mode converter is presented and verified using a commercial full-wave electromagnetic solver.","PeriodicalId":383636,"journal":{"name":"2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130082403","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}

Findings reveal that for highly resonant objects, the resonance frequency obtained using CMA approaches the natural resonance frequency obtained using SEM.

The harmonic sensor has a 3D form factor, is constructed from printed circuit board pieces, and operates at 1.2 GHz (receive) and 2.4 GHz (transmit). The system operates by interrogating a sensor that is embedded in the concrete under test using a wireless reader and correlating variation in signal strength received back from the sensor with the complex permittivity of the concrete. Empirical results from tests of sand-water mixtures, sand-ionic solution mixtures, and cement mortar mixtures are presented. The data demonstrate high sensitivity in signal strength versus moisture and ionic content for relatively low, realistic moisture conditions.","PeriodicalId":383636,"journal":{"name":"2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125242551","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}
