This paper deals with the response of a stratified cold plasma to an infinite plane electromagnetic wave incident vertically on the ionization. The transient response is found by utilizing a multiple-scattering technique, by summing a large number of scalar functions described as first scatter, second scatter, etc. A generalized formula is used for finding the nth scattered field in terms of the (n-1)th scattered field. Specifically two cases are considered: the generalized response of a half-space of uniform electron density to any incident wave expressible in a Maclaurin series, and the response of an infinite region whose electron density increases exponentially with height to an incident step-modulated sine wave.
