    "abstract": "The recent surface plasmon entanglement experiment [E. Altewischer et al.,\nNature (London) 418, 304 (2002)] is theoretically analyzed. The entanglement\npreservation upon transmission in the non-focused case is found to provide\ninformation about the interaction of the biphoton and the metallic film. The\nentanglement degradation in the focused case is explained in the framework of a\nfully multimode model. This phenomenon is a consequence of the\npolarization-selective filtering behavior of the metallic nanostructured film.",
