Book Synopsis Electromagnetic Wave Scattering from Random Rough Surfaces by : Nicolas Pinel
Download or read book Electromagnetic Wave Scattering from Random Rough Surfaces written by Nicolas Pinel and published by John Wiley & Sons. This book was released on 2013-12-02 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic wave scattering from random rough surfaces is an active, interdisciplinary area of research with myriad practical applications in fields such as optics, acoustics, geoscience and remote sensing. Focusing on the case of random rough surfaces, this book presents classical asymptotic models used to describe electromagnetic wave scattering. The authors begin by outlining the basic concepts relevant to the topic before moving on to look at the derivation of the scattered field under asymptotic models, based on the Kirchhoff-tangent plane, in order to calculate both the scattered field and the statistical average intensity. More elaborated asymptotic models are also described for dealing with specific cases, and numerical results are presented to illustrate these models. Comparisons with a reference numerical method are made to confirm and refine the theoretical validity domains. The final chapter derives the expressions of the scattering intensities of random rough surfaces under the asymptotic models. Its expressions are given for their incoherent contributions, from statistical calculations. These results are then compared with numerical computations using a Monte-Carlo process, as well as with experimental models, for sea surface backscattering. Contents 1.

Electromagnetic Wave Propagation Panel. Specialists' Meeting and published by . This book was released on 1988 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topic of scattering and propagation in random media is one that has implications for the design, development and operation of most military systems that radiate energy as a means of accomplishing their funtion. Primary emphasis is on scattering and transmission in the atmosphere; however, other related random medium effects are not excluded. Modern methods of characterizing random media, mathematical methods and their applicability, effects on electromagnetic waves and the interpretation of these effects to specific system applications are described. The region of the spectrum considered is essentially unlimited and ranges from very long waves to optics. The performance of existing surveillance communication and navigation systems as well as the design of future systems is influenced by the propagation of energy via random media. An understanding of the nature of the medium and its impact on system design and performance is essential to the NATO community.

Available in PDF, EPUB and Kindle. Book excerpt: I am pleased to present a work which marks a milestone in the history of public works and, more precisely, in that of permanent structures—a comprehensive dictionary of Civil Engineering terms. Since the beginning of time, Man has always tried to find a means to clear the obstacles which nature erected to displace him. With the first tree trunk thrown across a river, man sought to improve the crossing structure. After the invention of the wheel, and to satisfy his thirst for conquest (Roman ways), and comfort (aqueducts), man built bridges that became a preremptory necessity to move quickly. Thus, Man started to build wooden and masonry works. With the passing centuries, the builders became masters in the art of building masonry works. Then came the Industrial Revolution and the advent of the steel (1864), which was closely followed by the invention of the reinforced concrete (1855). The need for railways and improving the road network inspired great works of crossing such as viaducts and tunnels. The boom of the railway network and the development of the car required the construction of an increasing number of new structures. This phenomenon continues today with hundreds of structures built each year throughout the world.

Book Synopsis Wave Scattering from Rough Surfaces by : Alexander G. Voronovich
Download or read book Wave Scattering from Rough Surfaces written by Alexander G. Voronovich and published by Springer Science & Business Media. This book was released on 2013-03-07 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the fIrst edition of this book was published in the 1994, the theory of wave scattering from rough surfaces has continued to develop intensively. The community of researchers working in this area keeps growing, which provides justifIcation for issuing this second edition. In preparing the second edition, I was challenged by the problem of se lecting new material from the many important results obtained recently. Even tually, a new section was added to the central Chap. 6 of this book. This sec tion describes the operator expansion technique put forward by M. Milder, which conforms well with the general approach adopted in the book and which to my mind is one of the most promising. Remote sensing of the terrain and ocean surface represents one of the most important and interesting challenges to the theory of wave scattering from rough surfaces. Rapid progress in electronics results in sensors with new capabilities. New powerful computers and data communication systems allow more sophisticated data processing techniques. What information about soil or air-sea interaction processes can be obtained from gigaflops of data streaming from air-or space-borne radars? To use this information efficiently, one cannot rely entirely on heuristic approaches and needs adequate theory. I hope that this book will contribute to progress in this important area.
