Two related nonlinear problems regarding the behavior of an ionizing rf wave in a plane plasma slab and in a cylindrical plasma column, each produced by the wave, are analyzed in the normal-skin-effect approximation. In an unbounded volume such plasmas can exist only in the field of slow TM waves under the condition that the dielectric function at the center of the column (or slab) changes sign in the wave field. For the plane slab the phase velocity of the wave is a resonant function of the frequency and amplitude. A cylindrical plasma column can exist in a waveguide in two forms: as a weak column, if the dielectric function is positive over the entire plasma volume and in a strong form, if the dielectric function is negative at the center of the column and there is an abrupt change in sign in the cross section. A transition from one form to the other occurs in the field of a fast wave and is characterized by a change in the spatial structure of the plasma.
