Book Synopsis Theoretical Methods for Determining the Interaction of Electromagnetic Waves with Structures by : J.K. Skwirzynski
Download or read book Theoretical Methods for Determining the Interaction of Electromagnetic Waves with Structures written by J.K. Skwirzynski and published by Springer. This book was released on 1981-10-31 with total page 936 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains almost complete proceedings of the NATO Advanced Study Institute (ASI) organised in 1979 to bring together principal innovators and numerous users of mathematical techniques for analysing the interaction of electromagnetic waves with engineering and biological structures. The mathematical disciplines which can be brought to bear on these problems necessitate examination of effectiveness, convergence and robustness of the derived analytic and num~rical algorithms. The aim of this ASI was to give a clear and up-to-date tutorial presentation of available techniques, and to bring together interested scientists, engineers and mathematiciaris, to discuss together their experience and to ensure wider familiarity with the subject. Our programme consists of three distinct yet related parts. The first two of these reflect two somewhat different methods applicable for different ranges of L/A, where L represents a characteristic dimension of a structure and A is a representative wavelength-of radiation. The third part deals with the specific problem of biological interaction. In the first part (Low and Intermediate Frequency Applications) we offer tutorial texts and user-oriented discussions on main techniques and problems concerning: radiation, scattering, aperture penetration, inverse scattering, using moment methods and their developments. The approach to the high frequency applications forms the subject of the second part of this volume, concentrating mainly on the geometrical theory of diffraction (GTD). There are three main variants of the GTD: uniform theory of diffraction (UTD), uniform asymptotic theory (liAT) , spectral theory of diffraction (STD).

Book Synopsis Analytical Techniques Used to Calculate the Fields Due to Refraction and Diffraction of Electromagnetic Waves by : J. L. Gribble
Download or read book Analytical Techniques Used to Calculate the Fields Due to Refraction and Diffraction of Electromagnetic Waves written by J. L. Gribble and published by . This book was released on 1984 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis provides a compendium of analytical techniques which can be used to calculate the fields that are created when an electromagnetic wave is incident upon a physical object. Quasi-optical techniques (Geometrical Theory of Diffraction and Uniform Theory of Diffraction) are analyzed along with the more classical physical and geometrical optics techniques (Kirchoff Diffraction Theorem, Sommerfeld Diffraction Theorem, Fourier optics, and geometrical optics). The approximations that are used in each technique along with the regions of the electromagnetic spectrum where each technique can be applied are emphasized. Each technique is derived and all are shown to be ultimately dependent upon the validity of Maxwell's equations. The Fourier optics and Geometric Theory of Diffraction techniques are shown to be direct mathematical extensions of the Sommerfeld Diffraction Theorem. Each technique is then applied to a simple example problem. The technique of Fourier optics is shown to be very powerful while remaining mathematically simple. The Fresnel and Fraunhoffer approximations are most readily understood when this technique is used. It is also shown that the Geometric Theory of Diffraction and Uniform Theory of Diffraction are capable of giving accurate results when the physical object has a complex geometry. Keywords include: Diffraction; Millimeter waves; and Microwave optics.
Book Synopsis Fundamentals of the Physical Theory of Diffraction by : Pyotr Ya. Ufimtsev
Download or read book Fundamentals of the Physical Theory of Diffraction written by Pyotr Ya. Ufimtsev and published by John Wiley & Sons. This book was released on 2007-02-09 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first complete and comprehensive description of the modern Physical Theory of Diffraction (PTD) based on the concept of elementary edge waves (EEWs). The theory is demonstrated with the example of the diffraction of acoustic and electromagnetic waves at perfectly reflecting objects. The derived analytic expressions clearly explain the physical structure of the scattered field and describe in detail all of the reflected and diffracted rays and beams, as well as the fields in the vicinity of caustics and foci. Shadow radiation, a new fundamental component of the field, is introduced and proven to contain half of the total scattered power.

Book Synopsis Electromagnetic Wave Theory by : J. C. Brown
Download or read book Electromagnetic Wave Theory written by J. C. Brown and published by Elsevier. This book was released on 2013-10-22 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic Wave Theory, Part 2 contains the proceedings of a Symposium on Electromagnetic Wave Theory held at Delft, The Netherlands in September 1965. The symposium provided a forum for discussing electromagnetic wave theory and tackled a wide range of topics, from propagation in nonlinear media to electromagnetic wave propagation and amplification in solid-state plasmas. Electromagnetic waves in nonlinear transmission lines with active parameters are also considered, along with the phase dependence of maser active material Q-factor on pump intensity and frequency. Comprised of four sections, this volume begins with an analysis of two modes of propagation that are coupled through parametric modulation in nonlinear media. The discussion then turns to symmetry restrictions in nonlinear, non-absorbing, non-dispersive media; nonlinear interaction between two beams of plane electromagnetic waves in an anisotropic medium; radiation in periodically non-stationary media; and electromagnetic wave propagation in time-varying media. Subsequent chapters explore the diffraction of electromagnetic waves by plasma structures; resonant electromagnetic scattering from gyrotropic plasmas; scattering and transmission of electromagnetic waves at a statistically rough boundary between two dielectric media; and developments in wavefront reconstruction. This book will be useful for students, practitioners, and researchers in physics.

Book Synopsis Uniform Geometrical Theory of Diffraction by :
Download or read book Uniform Geometrical Theory of Diffraction written by and published by . This book was released on 1987 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Keller's geometrical theory of diffraction (GTD) represents a major breakthrough in solving a wide variety of electromagnetic (EM) radiation and scattering problems at high frequencies. In particular, the GTD is an extension of geometrical optics to include a class of diffracted rays via a generalization of Fermat's principle. These diffracted rays are initiated, for example, from geometrical and electrical discontinuities in a scatterer, or from points of grazing incidence on smooth convex parts of the scattering surface. However, being a purely ray optical theory, the original GTD is overcome via the uniform version of the GTD (i.e., UTD) which requires the diffracted field to make the total high frequency field continuous across the optical shadow boundaries. The UTD solutions for the diffraction by edges and smooth convex surfaces are reviewed in detail after introducing the basic concepts of GTD. Results based on a few additional UTD solutions are also presented together with a few selected applications of these UTD solutions to predict the EM radiation and scattering from complex structures.
