Electromagnetic Pulse Propagation In Casual Dielectrics

de G.C. Sherman e Kurt E. Oughstun

145,09€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This research monograph presents a systematic treatment of the theory of the propagation of transient electromagnetic fields (such as optical pulses) through dielectric media which exhibit both dispersion and absorption. The work divides naturally into two parts. Part I presents a summary of the fundamental theory of the radiation and propagation of rather general electromagnetic waves in causal, linear media which are homogeneous and isotropic but which otherwise have rather general dispersive and absorbing properties. In Part II, we specialize on the propagation of a plane, transient electromagnetic field in a homogeneous dielectric. Although we have made some contributions to the fundamental theory given in Part I, most of the results of our own research appear in Part II. The purpose of the theory presented in Part II is to predict and to explain in explicit detail the dynamics of the field after it has propagated far enough through the medium to be in the mature-dispersion regime. It is the subject of a classic theory, based on the research conducted by A. Sommerfeld and L.

Electromagnetic Surface Excitations - Proceedings Of An International Summer School At The Ettore Majorana Centre, Erice, Italy, July 1-13, 1985

118,59€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This volume is based on lectures and contributed papers presented at the Eighth Course of the International School of Materials Science and Tech nology that was held in Erice, Sicily, Italy at the Ettore Majorana Centre for Scientific Culture during the period 1-13 July 1985. The subject of the course was "Electromagnetic Surface Excitations". Forty lectures were given by eleven distinguished scientists and engineers from France, Italy, the United Kingdom, and the United States. In addition to the lectur ers, approximately fifty participants representing eleven different countries throughout the world t. ook part in the course. Short contributed papers were presented by seventeen participants on the results of their own re search. The subject of the Course is of great importance for both pure science and for practical applications such as telecommunications. A technolog ical revolution is occurring in which the transmission of information by means of electrical currents travelling in copper wires is being replaced by transmission by means of light travelling in objects known as optical wave guides. The manipulation and processing of the light signals prior and subsequent to transmission through the wave guide has resulted in a technology often referred to as integrated optics. Important to the opera tion of integrated optics devices is the behavior of electromagnetic waves near surfaces and interfaces. One of the goals of the course was to further the dialogue between engineers and physicists in common areas of interest related to the propagation of electromagnetic waves along surfaces.

Recent Developments In Surface Acoustic Waves - Proceedings Of European Mechanics Colloquium 226, University Of Nottingham, U. K., September 2-5, 1987

118,59€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The topic of surface waves lies at the interface between a number of disci plines - physics, theoretical and applied mechanics, electroacoustics, ap plied mathematics, surface science and seismology. This volume, based on papers delivered at European Mechanics Colloquium 226, reflects this diversity in approach and background, while showing strong links between phenomena arising from different fields. The emphasis is on recent de velopments such as nonlinear and other nonclassical effects,which have great importance for both pure science and for applications such as signal processing, nondestructive evaluation and seismic studies. In recent years there has been considerable progress in the mathe matical treatment of nonlinear effects, of viscoelastic and of more novel constitutive effects which modify the predictions of linear elastic and piezo electric theory for surface acoustic wave (SAW) propagation. A number of these themes serve to group the contents of this volume. Part I contains recent advances in the rigorous mathematical treatment of nonlinearity, together with a paper giving experimental results showing the need for further theoretical development. Part II deals with anisotropic elasticity, showing that even the linear theory presents many possible behaviours, which are still not fully categorized.

Mechanics Of Continua And Wave Dynamics

de L. Brekhovskikh e V. Goncharov

95,40€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This text is based on lectures given by the authors to students of the Physico Technical Institute in Moscow in the course of many years. Teaching mechan ics of continuous media to students in physics has some specific features. Un fortunately, the students rarely have enough time for this branch of science. Over a comparatively short period of time and without sophisticated mathe matics, the lecturer has to set forth the principal facts and methods of this rather important aspect of theoretical physics. The goal can be achieved only if the knowledge and intuition obtained by students in other courses has been mobilized efficiently. These observations have extensively been taken into account when classical as well as more contemporary and actively developing branches of mechanics of continua are considered. The theory of wave propagation is the most important topic in mechanics of continua for those who work in the field of physics and geophysics. That is why most attention is paid to this topic in the main text as well as in numerous exercises. The propagation of various kinds of hydrodynamic, magnetohydro dynamic, acoustic and seismic waves is considered in some detail. We begin with simple questions and proceed to more complicated ones. Accordingly, we treat the elasticity theory first. In the limits this appears to be simpler than the mechanics of fluids. For further study of each topic the reader will find references in the bibliography.

Wave Scattering From Rough Surfaces

de Alexander G. Voronovich

95,40€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Diverse areas of physics and its applications deal with wave scattering at rough surfaces: optics, acoustics, remote sensing, radio astronomy, physics of solids, diffraction theory, radio and wave-propagation techniques, etc. The mathe matical description of relevant problems is rather universal and theoretical methods analysing this phenomenon form a definite area of mathematical physics. It was founded by Lord Rayleigh at the beginning of the 20th century and has been intensively developed since 1950 in response to practical needs. Modern theory involves, along with the classical methods, some new ap proaches with much more extensive possibilities. The theoretical methods describing wave scattering at rough surfaces repre sent the subject of this book. Having studied this area over many years, the author came to the conclusion that most of the results found in this theory can easily be obtained and comprehended in the framework of a rather universal scheme and this became the motive for writing the present monograph. The first half of the book deals with the classical results. However, several new problems are considered in connection with the methods used here (for example, some applications of the Rayleigh hypothesis and its relation to the Lippman argument). The second half is fully devoted to recent results presented in papers but not yet in books. For this reason the author hopes that the present book will be of interest to both newcomers and experts in this area.

Acoustics Of Layered Media Ii - Point Sources And Bounded Beams

de Leonid M. Brekhovskikh e Oleg A. Godin

95,40€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This is the sequel to our book Acoustics of Layered Media I: Plane and Quasi Plane Waves (Springer Ser. Wave Phenom. , Vol. 5). Taken together, these two monographs present a systematic exposition of the theory of sound propagation in inhomogeneous media, which starts from first principles and includes recent results. More advanced topics are considered in this second volume. Although the theory of wave beams and fields of localized sources is more sophisticated than the theory of quasi-plane waves, it embraces a much wider range of interesting problems that are also important for applications. We exploit the results of Acoustics of Layered Media I, as long as it is expedient to consider sound fields as a superposition of plane or quasi-plane waves. However, the knowledgeable reader will view this book as self-contained. Similar topics have been treated in the book by L. M. Brekhovskikh, Waves in Layered Media, the English version of the second edition of which was published by Academic Press in 1980. Since Waves in Layered Media became very popular, we have tried here to retain its spirit. However, the majority of this text is devoted to new material which reflects the significant progress of the theory during recent years. In particular, acoustic fields in a moving fluid are considered and much attention is paid to sound propagation in range dependent environments, which is currently on the leading edge of research activities.
