Abstract:	摘要： In this article, the polarization-conversion effects of a gammadion-shaped metasurface in transmission and reflection modes are discussed. In our experiment, the polarization-conversion effect of a gammadion-shaped metasurface is investigated because of the contribution of the phase and amplitude anisotropies. According to our experimental and simulated results, the polarization property of the first-order transmitted diffraction is dominated by linear anisotropy and has weak depolarization; the first-order reflected diffraction exhibits both linear and circular anisotropies and has stronger depolarization than the transmission mode. These results are different from previously published research. The Mueller matrix ellipsometer and polar decomposition method will aid in the investigation of the polarization properties of other nanostructures. 其他題名： Sci Rep 出版者： London: Nature Publishing Group UK 出版日期： 2016-02-26 出處： Scientific reports, 2016-02, Vol.6 (1), p.22196, Article 22196 資源來源： SpringerLink Journals Open Access 版權： The Author(s) 2016 版權： Copyright Nature Publishing Group Feb 2016 版權： Copyright © 2016, Macmillan Publishers Limited 2016 Macmillan Publishers Limited 識別號： ISSN: 2045-2322 識別號： EISSN: 2045-2322 識別號： DOI: 10.1038/srep22196 識別號： PMID: 26915332
