Attenuation of Longitudinal Electroacoustic Waves in a Plasma.
Abstract
Longitudinal waves that can be readily excited in a plasma are associated with a large number of important physical applications. One of these applications includes the use of electroacoustic probes to determine the electron density in the boundary layer of re-entry flow fields. Also, the interaction of intense laser radiation with plasmas can excite longitudinal wave instabilities and produce an anomalous resistivity of a plasma. Two mechanisms responsible for the attentuation of longitudinal waves are collisionless (Landau) damping and electron-neutral collisions. The paper is devoted to an analytical study of the spatial decay of these longitudinal waves using an explicit representation for the electric field vector. (Modified author abstract)
