IONIZED SHOCK FRONT ANALYSIS. PART IV. PROPAGATION AND REFLECTION CHARACTERISTICS OF A UNIFORM MEDIUM WITH A NONLINEAR ELECTRICAL CONDUCTIVITY
Abstract
An analysis (AD-252 235) dealing with the effect of a nonlinear electrical conductivity on the propagation of a plane electromagnetic wave through a semi-infinite uniform medium, is reformulated and extended to include the effects of the nonlinear conductivity on the reflecting properties of the interface separating the plasma from free space. Attention was restricted to small degrees of the nonlinearity. The solutions of the equations indicate the following effects of a nonlinear electrical conductivity: the wave number and attenuation factor of the transmitted wave may be significantly increased; the magnitude of the transmission coefficient may be significantly reduced; and the change in phase across the interface, relative to the linear conductivity result may be either positive or negative, depending on whether the signal frequency is greater than or less than the plasma frequency.
