This paper proposes a scheme for fast RCS measurement with multiple bands based on the microwave photonic inverse synthetic aperture radar (ISAR). With the advantages of frequency reconfigurable and large bandwidth provided by microwave photonics, RCS can be obtained from the multi-band and ultra-high resolution ISAR image based on Parseval's theorem with fast speed and high precision. In a proof-of-concept experiment, the target's RCS characteristics in the X, Ku, and Ka bands are analyzed, showing that the ISAR-based RCS measurement precision is about 0.5 dBsm in the near-field measurement with a measurement speed of about 70 ms each time.","PeriodicalId":350271,"journal":{"name":"2022 20th International Conference on Optical Communications and Networks (ICOCN)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130617448","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}

However, the polarization-dependent unit cell design is one of the main challenges toward multi-polarization plasmonic metalenses especially for high transmission efficiency arrays design. In this paper, to overcome this obstacle, an annular slot element-type metallic metasurface is proposed for the design of high efficient metalens in the microwave band. The meta-atom with different layer metal-dielectric-metal hybrid structure is investigated and compared with each other by using full-wave simulations. Besides, transverse magnetic (TM) and transverse electric (TE) mode of unit cell are specifically presented for transmission magnitude, phase distribution and power intensity. In order to fulfill the required phase profile to create metalens simultaneously with high transmission efficiency, four-layer sub-wavelength metallic metasurface with varying outer radius of slot-element is selected. An ultra-thin microwave metalens operating around 9GHz is thus designed and its focusing performances such as focusing power intensity, full-width at half-maximum of its focusing spot and focusing efficiency are also analyzed with full-simulation microwave studio. The studies here on microwave metalens based on proposed meta-atom provide new ways to develop polarization-insensitive high transmission meta-devices in low spectrum.","PeriodicalId":350271,"journal":{"name":"2022 20th International Conference on Optical Communications and Networks (ICOCN)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116491564","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}
