Plasma Inverse Scattering Theory

The object of the report is to calculate the electron density profile of plane stratified inhomogeneous plasmas. The electron density profile is obtained through a numerical solution of the inverse scattering algorithm. The inverse scattering algorithm connects the time dependent reflected field resulting from a delta-function field incident normally on the plasma to the inhomogeneous plasma density. Examples show that the method produces uniquely the electron density on or behind maxima of the plasma frequency. It is shown that the delta-function incident field used in the inverse scattering algorithm can be replaced by a thin square pulse. (Author)
