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.

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).

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).

This volume presents a detailed, rigorous treatment of the fundamental theory of electromagnetic pulse propagation in causally dispersive media that is applicable to dielectric, conducting, and semiconducting media. Asymptotic methods of approximation based upon saddle point methods are presented in detail.

Helps both engineers and students improve their writing skills by learning to analyze target audience, tone, and purpose in order to effectively write technical documents This book introduces students and practicing engineers to all the components of writing in the workplace. It teaches readers how considerations of audience and purpose govern the structure of their documents within particular work settings. The IEEE Guide to Writing in the Engineering and Technical Fields is broken up into two sections: “Writing in Engineering Organizations” and “What Can You Do With Writing?” The first section helps readers approach their writing in a logical and persuasive way as well as analyze their purpose for writing. The second section demonstrates how to distinguish rhetorical situations and the generic forms to inform, train, persuade, and collaborate. The emergence of the global workplace has brought with it an increasingly important role for effective technical communication. Engineers more often need to work in cross-functional teams with people in different disciplines, in different countries, and in different parts of the world. Engineers must know how to communicate in a rapidly evolving global environment, as both practitioners of global English and developers of technical documents. Effective communication is critical in these settings. The IEEE Guide to Writing in the Engineering and Technical Fields Addresses the increasing demand for technical writing courses geared toward engineers Allows readers to perfect their writing skills in order to present knowledge and ideas to clients, government, and general public Covers topics most important to the working engineer, and includes sample documents Includes a companion website that offers engineering documents based on real projects The IEEE Guide to Engineering Communication is a handbook developed specifically for engineers and engineering students. Using an argumentation framework, the handbook presents information about forms of engineering communication in a clear and accessible format. This book introduces both forms that are characteristic of the engineering workplace and principles of logic and rhetoric that underlie these forms. As a result, students and practicing engineers can improve their writing in any situation they encounter, because they can use these principles to analyze audience, purpose, tone, and form.
