Abstract: We use a single-layer thick metallic metasurface to design the 0-,45- and 90-degree polarizers with transmission efficiencies exceeding 95% based on the bright electric dipole resonance and dark magnetic dipole resonance. In addition, we utilize a bilayer metallic metasurface (forming an efficient Fabry-Perot resonator) to propose a circularly polarizing dichroism waveplate (CPDW). The circular polarization dichroism (CPD = I-RCP - I-LCP) in the transmission mode at 1.6 mu m wavelength reaches 89% and the extinction ratio (ER = I-RCP/I-LCP) is 830:1. These four polarizing elements are integrated to form a full Stokes pixel that almost accurately measures arbitrary polarized light at lambda(0) = 1.6 mu m (including elliptically polarized light).
