Employing a novel Huygens’ architecture with miniaturized size and improved tuning range, we achieve wideband, linear-phased, highly transmissive elements capable of generating a large range true-time-delay. This allows us to construct a dual-polarized achromatic metalens with a large numerical aperture. As a proof of concept, we design a dual-polarized achromatic metalens for which the focal length is maintained at $6.4pm 0.15lambda_{c}$ across the operation band (K-band, 21.5-26 GHz), where $lambda_{c}=12.5$ mm is the wavelength corresponding to the center frequency of 24 GHz. The simulated focusing efficiency is over 65% across the operation bandwidth. The combination of the miniaturized unit cell and increased tuning range allows this dual-polarized achromatic metasurface to have a numerical aperture of 0.64 – which is the highest known among achromatic metalenses in the microwave region. This metasurface shall find attractive applications in broadband imaging and communication at microwave and mm-wave frequencies.","PeriodicalId":137840,"journal":{"name":"2022 International Symposium on Antennas and Propagation (ISAP)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126747001","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}
