About this Item: John Wiley & Sons, Inc, New York, Hardcover. Condition: Very Good. Dust Jacket Condition: Good. 1st Edition. First edition, hardcover, front hinge has been repaired, has very slight skew to spine, slight bumps to spine ends and corners, and some slight shelfwear to edges, otherwise a solid VG copy in Good dustjacket which has small chips to spine ends and corners. In the literature on electromagnetic wave propagation, these oppositely propagating waves are often called "bidirectional beams" [1,2] whereas in the acoustic literature they are usually called "one-way wave fields" []. In this paper, we use the latter terminology. If wave fields obeyed an inverse square law then no appreciable radiation would reach us from the rest of the Universe. In conclusion, electric and magnetic fields look simple in the near field region (they are just Coulomb fields, etc.) and also in the far field region (they are just electromagnetic waves).

In this paper we review the theory for electromagnetic one-way wave fields, including dissipation, and we derive reciprocity theorems for these one-way wave fields.

First we consider the special situation of a 2-D medium in which the medium parameters vary only in the lateral direction.

The wave-splitting procedure results in two one-way equations for the wave-field by: 4. Abstract. Acoustic reciprocity theorems have proved their usefulness in the study of forward and inverse scattering problems. The reciprocity theorems in the literature apply to the two-way (i.e.

The electromagnetic radiation wave fields E and B generated by the motion of charges are time-dependent and have leading terms of long range, which decay slowly at large distances. Professor Jean Van Bladel, an eminent researcher and educator in fundamental electromagnetic theory and its application in electrical engineering, has updated and Directional Decomposition of Electromagnetic & Acoustic Wave-Fields book his definitive text and reference on electromagnetic fields to twice its original content.

This new edition incorporates the latest methods, theory, formulations, and applications that relate to today's technologies/5(3). [1] We describe several newly developed methods for propagation analysis of electromagnetic plasma waves. We make use of singular value decomposition (SVD) technique and we determine the wave vector direction, ellipticity and directions of axes of the Directional Decomposition of Electromagnetic & Acoustic Wave-Fields book ellipse, Directional Decomposition of Electromagnetic & Acoustic Wave-Fields book refractive index, transfer function of electric antennas, estimators of the planarity of polarization, and.

The hydrostatic approximation filters all acoustic modes except the Lamb wave (an acoustic mode that propogates only in the horizontal direction). As the Lamb wave is close in speed to the external gravity waves, it can generally be subsumed into an algorithm for gravity waves, and so is of little consequence to ocean model algorithms.

Reciprocity theorems for electromagnetic and acoustic wave fields have been formulated at the end of the nineteenth century by H. Lorcntz and J. Rayleigh, respectively. A reciprocity theorem interrelates the sources and wave fields in two admis- sable physical and/or computational states in one and the same by: A new directional decomposition of the acoustic 3D wave equation is derived for spherically symmetric geometries, where the wave fields do not need to possess such a symmetry.

This provides an alternative basis for various applications of techniques like invariant embedding and time domain Green functions in spherically symmetric : Peter Olsson.

The book is designed so that the reader with an familiarity with either Maxwell's Equations or the equation of sound waves in fluid dynamics can follow the developments in both fields without difficulty.

The book also includes chapters related to the modern technology of geophysical imaging, based on seismic and electromagnetic migration. This volume is unique in its focus on providing a link between the methods used in gravity, electromagnetic, and seismic imaging and inversion, and represents an exhaustive treatise on inversion theory/5(2).

Properties of Electromagnetic Waves 1. The fields E and B and are perpendicular to the direction of propagation v an electromagnetic wave is a transverse wave. E and B are perpendicular to each other in a manner such that E × B is in the direction of v em. The wave travels in vacuum at speed v em = c 4.

The history of electromagnetic theory begins with ancient measures to understand atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to explain the phenomena.

Scientific understanding into the nature of electricity grew throughout the eighteenth and nineteenth centuries through the work of researchers such as Coulomb, Ampère.

A sensor array is a group of sensors, usually deployed in a certain geometry pattern, used for collecting and processing electromagnetic or acoustic signals. The advantage of using a sensor array over using a single sensor lies in the fact that an array adds new dimensions to the observation, helping to estimate more parameters and improve the estimation performance.

The reciprocity theorems for acoustic, elastodynamic, and electromagnetic Wave fields in linear, time-invariant configurations show a common structure that can serve as a guideline for the development of computational methods for these wavefields.

To this end, the wave field reciprocity theorems are. The properties of electromagnetic ﬁelds and waves are most commonly discussed in terms of the electric ﬁeld E(r,t) and the magnetic induction ﬁeld B(r,t).

The vector r denotes the location in space where the ﬁelds are evaluated. Similarly, t is the time at which the ﬁelds are evaluated. Note that the choice of E and B is ar.
