Keywords:plasmon, chirality, polarization measurement

We experimentally visualized the spatial structures of the degree of circular polarization P_cpof the optical field generated by two-dimensional chiral gammadion gold nanostructures, and also measured the spectral properties of ∫P_cpdS/S (spatially averaged P_cp).
