    "abstract": "The quantization of the scalar and electromagnetic fields in the presence of\na parabolic mirror is further developed in the context of a geometric optics\napproximation. We extend results in a previous paper to more general\ngeometries, and also correct an error in one section of that paper. We\ncalculate the mean squared scalar and electric fields near the focal line of a\nparabolic cylindrical mirror. These quantities are found to grow as inverse\npowers of the distance from the focus. We give a combination of analytic and\nnumerical results for the mean squared fields. In particular, we find that the\nmean squared electric field can be either negative or positive, depending upon\nthe choice of parameters. The case of a negative mean squared electric field\ncorresponds to a repulsive Van der Waals force on an atom near the focus, and\nto a region of negative energy density. Similarly, a positive value corresponds\nto an attractive force and a possibility of atom trapping in the vicinity of\nthe focus.",
