Abstract The metamaterial can be used as a device for selecting circularly polarized light because of its unique properties, namely circular polarizer. With the increasing importance of polarization resolved imaging system, circular polarizers have been applied to enhanced contrast, circular polarization microscopy and detection of biomolecules such as amino acid, DNA and glucose which have inherent chiral structures. Especially, circular polarizers operating at visible wavelength have attracted much attention because they are exploited as crucial optical components to control the polarization state of light in the complex display systems. However, the traditional circular polarizer for obtaining circularly polarized light has great limitations, such as bulky configuration, narrow working bandwidth and so on, which greatly limits their development to some extent. Recently,the development of broadband circular polarizers has been promoted with the proposed helical structures and stack structures in metamaterials.The polarization principles of two such kinds of wideband wideband structures are introduced. The numerical simulation and experimental research progress of two such kinds of wideband structures as circular polarizers are reviewed in detail.
