TRANSIENT SIGNAL PROPAGATION IN LOSSLESS, ISOTROPIC PLASMAS. VOLUME II.

Abstract

The asymptotic behavior of transient signal propagation in lossless, isotropic plasmas is discussed at length for a typical input signal of a step modulated sine wave. A generalized saddlepoint integration is carried out that gives a continuous solution for the dispersed signal everywhere except at the signal wavefront. The solution for the wavefront is obtained by using a high-frequency expansion technique. Universal curves are presented for the behavior of the distorted signal as a function of the plasma frequency, signal frequency, and propagation distance. The solution is a very good approximation for plasma propagation length that are long compared to a wavelength. (Author)
