    "abstract": "Though both theoretical and experimental investigations have revealed the\nsuperluminal behavior of evanescent electromagnetic waves, there are many\ndisputes about the physical meaning and validity of such superluminal\nphenomenon, which is due to the fact that the traditional investigations are\nbased on the theory of tunneling time, and concerned with the problem of what\nthe group velocity of evanescent waves means. In this paper, by studying the\nquantum probability amplitude for photons to propagate over a spacelike\ninterval along an undersized waveguide, we present theoretical evidence for\nsuch superluminality.",
