    "abstract": "Generation of wake fields by a short electromagnetic pulse in a plasma with\nan inhomogeneous background magnetic field and density profile is considered,\nand a wave equation is derived. Transmission and reflection coefficients are\ncalculated in a medium with sharp discontinuities. Particular attention is\nfocused on examples where the longitudinal part of the electromagnetic field is\namplified for the transmitted wave. Furthermore, it is noted that the wake\nfield can propagate out of the plasma and thereby provide information about the\nelectron density profile. A method for reconstructing the background density\nprofile from a measured wake field spectrum is proposed and a numerical example\nis given.",
