In this paper, we distinguish the cavity’s resonant frequency using transmitting signal amplitude. This frequency is proportional to the watercut of water-oil or water-gas in multi-phase flows. To prove the concept, a resonant cavity sensor (RCS) was fabricated. To improve the transmission coefficient of RCS, an impedance matching circuit was also implemented. Since there is no feedback in the sensing chain, this method is very fast. Moreover, reducing the number of elements leads to a lower cost.","PeriodicalId":371560,"journal":{"name":"2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128068857","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 proposed framework uses a local DG scheme to discretize the (non-linearly) coupled system of the Poisson equation (in electric potential) and the drift-diffusion (DD) equations (in charge densities) in space. To reduce the computational requirements, a dual-mesh scheme, which uses a dense mesh for the DD equations and a much coarser mesh for the Poisson equation, is used. Furthermore, an implicit-explicit time integration scheme, which allows for a significantly larger time-step size, is utilized to efficiently account for the extremely long response time of OECTs. Numerical results are provided to demonstrate the applicability and accuracy of the proposed solver.","PeriodicalId":371560,"journal":{"name":"2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125587941","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 device is a reflective semiconductor chip composed of small two-stage phase delay cavities filled with electrically biased liquid crystal.

This enables each cavity to delay the fields in each stage by as much as 360 degrees. As a result, the two-stage cavity allows nearly independent scanning in two orthogonal planes. The structure operates at a wavelength of 1550nm and is manufactured using a standard damascene process.","PeriodicalId":371560,"journal":{"name":"2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125802498","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}

To achieve the conjugated input impedance match between antenna structure and Monza-4 chip (7.17—j74.22 Ω at 915 MHz), the proposed antenna was optimized by coarsely controlling the positions of vias and fine-tuning the gap of coupled patches. To further reduce the height or the size of antenna, the design method based on the 3D-dipole current distribution was presented. Consequently, the proposed tag not only was miniaturized but also got a stable long read range (> 5.0 m) and a wide bandwidth of 71 MHz, regardless of different placed locations of tag on the human body. Adequate agreement between the simulation and measured results was verified experimentally.","PeriodicalId":371560,"journal":{"name":"2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI)","volume":"277 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115762858","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}
