	abstract = {We demonstrate optically thin quarter-wave plates built with metasurfaces that generate high-quality circularly polarized light over a broad wavelength range for arbitrary orientation of the incident linear polarization. The metasurface consists of an array of plasmonic antennas with spatially varying phase and polarization responses. Experimentally demonstrated quarter-wave plates generate light with a high degree of circular polarization (\&gt;0.97) from lambda = 5 to 12 mu m, representing a major advance in performance compared to previously reported plasmonics-based wave plates.},
