Available in PDF, EPUB and Kindle. Book excerpt: Approximate solutions are obtained for the transient fields in an infinite or semi-infinite conducting medium excited by a step-modulated sinusoidal plane wave. A saddle point method is used to obtain a solution which is valid for relatively large times in the transient response, and a series expansion method is used to obtain a solution which is valid for small times in the transient response. A brief discussion is included on the signal velocity in a conducting medium. (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.

Available in PDF, EPUB and Kindle. Book excerpt: During the last twenty years the lifestyle of a large portion of the inhabitants of our planet has changed dramatically. This would never have been possible without the massive use of electronic and photonic technology, telecommuni cations, and computers. These disciplines are designed to code, transmit, detect, decode, and process signals and related information, and can be broadly addressed as information science and technology. In the sophisticated society in which we live and operate, this science is diffused transversely and plays a major role in almost every human activity. Information science and technology is the basis of a powerful industry that does not suffer the shortcomings of more traditional human enterprises. Information is a renewable source and its control and processing rely on software codes, which are a creation of the mind, and on related hardware, incredibly sophisticated but made out of simple, abundant materials. The rate of change and transformation of this industry is the highest mankind has ever experienced, and it requires not only the replacement of technologies but also a continuous updating of expertise to keep up with the rapid transformation. There is no doubt that this calls for a change in university training, to avoid students graduating at an already obsolete level.

This book was released on 2012-12-06 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: tion of fields as a product of coordinate-dependent and time-dependent factors. The temporal variations of both media and fields are given by Fourier expansions. The successes of radiotechnique provided fertile ground for the dominance of sinusoidal waves in wave physics. This approach proved to be a powerful the oretical tool, since researchers were dealing with long trains of slowly varying quasi-monochromatic waves. However, the success of this concept and the stan dardizability of related designs engendered a peculiar psychological hypnosis of Fourier electromagnetics, which took over as a model for wave phenomena in such cross-discipIlnary areas of physics as optics and acoustics. Yet in providing a description of alternating fields, the presentation of such fields in terms of traveling waves with frequency wand wave number k is not a law of nature. One can see that such a presentation is not even a logical corollary of Maxwell's equations. What is more, this approach has become inadequate today for the analysis of fields excited by ultrashort transients in continuous media.

This book was released on 2012-12-06 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sixth Conference on Ultra-Wideband, Short-Pulse Electromagnetics (UWB SP6), chaired by Eric Mokole of the United States Naval Research Laboratory (NRL) and hosted by the NRL and the United States Naval Academy (USNA), was held at the USNA in Annapolis Maryland (USA) from 3-7 June 2002. UWB SP6 was part of the AMEREM 2002 Symposium, chaired by Terence Wieting of the NRL. AMEREM 2002 continued the series of international conferences that were held in: Brooklyn New York at the Polytechnic University in 1992 and 1994; Albuquerque New Mexico in 1996 as part of AMEREM '96; Tel-Aviv Israel in 1998 as part of EUROEM '98; and Edinburgh Scotland in 2000 as part of EUROEM 2000. The next conference (UWB SP7) will be held from 12-16 July 2004 at Otto von Guericke University in Magdeburg Germany (EUROEM 2004) and will be chaired by Frank Sabath. The purpose of these meetings is: to focus on advanced technologies for the generation, radiation, and detection of ultrawideband (UWB) short-pulse signals, taking into account their propagation about, scattering from, and coupling to targets and media of interest; to report on developments in supporting mathematical and numerical methods; and to describe current and potential future applications of the technology. The session topics of UWB-SP6 included electromagnetic theory, scattering, UWB antennas, UWB systems, ground penetrating radar (GPR), pulsed,. power generation, time-domain computational electromagnetics, UWB compatibility, target detection and discrimination, propagation through dispersive media, and wavelet and multi-resolution techniques.

Download or read book Seismic Wave Propagation in Stratified Media written by Brian Kennett and published by ANU E Press. This book was released on 2009-05-01 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic Wave Propagation in Stratified Media presents a systematic treatment of the interaction of seismic waves with Earth structure. The theoretical development is physically based and is closely tied to the nature of the seismograms observed across a wide range of distance scales - from a few kilometres as in shallow reflection work for geophysical prospecting, to many thousands of kilometres for major earthquakes. A unified framework is presented for all classes of seismic phenomena, for both body waves and surface waves. Since its first publication in 1983 this book has been an important resource for understanding the way in which seismic waves can be understood in terms of reflection and transmission properties of Earth models, and how complete theoretical seismograms can be calculated. The methods allow the development of specific approximations that allow concentration on different seismic arrivals and hence provide a direct tie to seismic observations.
