A COMPARISON OF SEVERAL APPROXIMATIONS FOR THE DETERMINATION OF PLASMA LAYER PROPERTIES FROM THE MEASURED ELECTROMAGNETIC TRANSMISSION COEFFICIENT

Abstract

Several commonly used approximations of the transmission coefficient of a uniform plasma slab are critically examined and are compared with a new approximation. It is shown that the new approximation, in addition to being very suitable for use on digital computers, gives much higher accuracy than any other one over most useful values of plasma and collision frequencies. A series of charts shows the regions of validity of each approximation in the plasma frequency-collision frequency plane for various amounts of error and slab thicknesses.
