Available in PDF, EPUB and Kindle. Book excerpt: Using contour integration techniques, the authors have calculated the transient response of a lossy homogeneous isotropic plasma to a unit step and a step-carrier sine wave. It was found that in the presence of losses the temporal step function response within the plasma does not approach zero for large time as for the collisionless case, but rather approaches unity. The rate at which the transient approaches the asymptotic value of unity is strongly dependent on the losses, being quite rapid for large losses and exceedingly slow for very small losses. This result has an important impact on the propagation of EMP through the plasma sheath around a reentry vehicle, and through the ionized region near a low altitude nuclear fireball. (Author).

Download or read book Transient Signal Propagation in Lossless Isotropic Plasmas Volume II written by Cap Haskell and published by . This book was released on 1966 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Available in PDF, EPUB and Kindle. Book excerpt: The concept of the wave packet is used to obtain some general results on the propagation of signals in dispersive media. The dispersion of a Gaussian carrier pulse and a square wave carrier pulse in an isotropic plasma is carried out using the wave packet concept. A general analysis of transient wave propagation in isotropic plasmas is given using Laplace transform methods. Solutions are given in terms of series solutions which may be expressed in terms of Lommel functions. Integral solutions which can be easily evaluated numerically are derived using the convolution theorem and using contour integration techniques. The solutions are useful for short dispersion lengths.

Available in PDF, EPUB and Kindle. Book excerpt: The long time transient response of a lossless, anisotropic plasma to a short electromagnetic pulse is given. The solution is obtained using the asymptotic saddle-point method and is restricted to the cases of propagation parallel to and those perpendicular to the static magnetic field. The results indicate that natural oscillations occur and that these oscillations asymptotically approach the plasma cutoff and resonance frequencies for long times. In addition, complicated transient polarization effects are present in the response signal. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The transient fields due to a dipole placed in lossless plasma and excited by a delta function or a step-modulated sine wave current source were obtained in closed form. Far field approximation was used in the case of step-modulated sine wave. An interesting problem of transmission and reflection of a step-modulated sinusoidal plane wave, when it is incident normally at the boundary of a semi-infinite plasma or a plasma slab was also included.

This book was released on 1972 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: A lumped circuit transmission line which simulates a plasma was developed. Analogies were established by comparing the equations for the propagation of voltage in the line and the propagation of electromagnetic waves in dispersive media. The network simulated the one-dimensional isotropic case in which the plasma was linear, homogeneous and lossless. Both bounded and unbounded plasmas were considered. The transient reflected and transmitted response was measured for the step carrier sine wave, the step function and the impulse inputs. Phenomena such as ringing and time delay were observed, both of which are related to the plasma frequency. Methods of obtaining plasma slab thicknesses were also investigated. (Author).
