    "abstract": "We report polarization tomography experiments on metallic nanohole arrays\nwith square and hexagonal symmetry. As a main result, we find that a fully\npolarized input beam is partly depolarized after transmission through a\nnanohole array. This loss of polarization coherence is found to be anisotropic,\ni.e. it depends on the polarization state of the input beam. The depolarization\nis ascribed to a combination of two factors: i) the nonlocal response of the\narray due to surface plasmon propagation, ii) the non-plane wave nature of a\npractical input beam.",
