The Plane Wave Spectrum Representation of Electromagnetic Fields


Book Description

Electrical Engineering/Electromagnetics The Plane Wave Spectrum Representation of Electromagnetic Fields A classic reissue in the IEEE/OUP Series on Electromagnetic Wave Theory Donald G. Dudley, Series Editor"I am pleased to see that the IEEE Press and OUP have secured the rights to republish this excellent monograph ... a long-cherished exposition on the angular spectrum concept."--James R. WaitThe purpose of this book is to explain how general electromagnetic fields can be represented by the superposition of plane waves traveling in diverse directions, and to illustrate the way in which this plane wave spectrum representation can be put to good use in treating various characteristic problems belonging to the classical theories of radiation, diffraction and propagation. The book offers a largely unified theory of a range of problems, solutions to all of which are obtained in forms at least patently capable of yielding numerical results by straightforward means. The reader is assumed to be competent at integration in the complex plane, but otherwise the discussion is virtually self-contained. The aim is to furnish the student of electromagnetic theory with a useful technical tool and a comparatively compact account of some interesting aspects of his discipline. The contents are presented in two parts. The first, under the heading of Theory, covers Preliminaries, Plane wave representations; and Supplementary theory. The second, with the heading Application, deals with Diffraction by a plane screen; Propagation over a uniform plane surface; Propagation over a two-part plane surface; The field of a moving point charge; and Sources of anisotropic media.

The Kiss of Death


Book Description

Chagas' disease has become one of the major public-health problems in Latin America. Current estimates are that sixteen to eighteen million people are infected. It is caused by a flagellate protozoan whose vector is the triatomine or vinchuca bug, locally referred to as the "kissing bug" because of its tendency to lodge on victims' faces during sleep. Although there is no cure for the chronic stage, the disease vectors can be controlled and possibly eliminated through improved hygiene and living conditions. No longer exclusive to Latin America, Chagas' disease is spreading to North America with the migration of infected bugs, hosts, transfusions, transplant organs, and changes in climate. The Kiss of Death is a thorough study of Chagas' disease with analysis of research involving epidemiology, entomology, parasitology, pathology, and immunology.




Industrial Metrology


Book Description

The subject of this book is surface metrology, in particular two major aspects: surface texture and roundness. It has taken a long time for manufacturing engineers and designers to realise the usefulness of these features in quality of conformance and quality of design. Unfortunately this awareness has come at a time when engineers versed in the use and specification of surfaces are at a premium. Traditionally surface metrology usage has been dictated by engineers who have served long and demanding apprenticeships, usually in parallel with studies leading to technician-level qualifications. Such people understood the processes and the achievable accuracies of machine tools, thereby enabling them to match production capability with design requirements. This synergy, has been made possible by the understanding of adherence to careful metrological procedures and a detailed knowledge of surface measuring instruments and their operation, in addition to wider inspection room techniques. With the demise in the UK of polytechnics and technical colleges, this source of skilled technicians has all but dried up. The shortfall has been made up of semi skilled craftsmen, or inexperienced graduates who cannot be expected to satisfy tradition al or new technology needs. Miniaturisation, for example, has had a pro found effect. Engineering parts are now routinely being made with nanometre surface texture and fiatness. At these molecular and atomic scales, the engineer has to be a physicist.




Electromagnetic Waves in Stratified Media


Book Description

International Series of Monographs in Electromagnetic Waves, Volume 3: Electromagnetic Waves in Stratified Media provides information pertinent to the electromagnetic waves in media whose properties differ in one particular direction. This book discusses the important feature of the waves that enables communications at global distances. Organized into 13 chapters, this volume begins with an overview of the general analysis for the electromagnetic response of a plane stratified medium comprising of any number of parallel homogeneous layers. This text then explains the reflection of electromagnetic waves from planar stratified media. Other chapters consider the oblique reflection of plane electromagnetic waves from a continuously stratified medium. This book discusses as well the fundamental theory of wave propagation around a sphere. The final chapter deals with the theory of propagation in a spherically stratified medium. This book is a valuable resource for electrical engineers, scientists, and research workers.

Wave Propagation and Scattering in Random Media


Book Description

Wave Propagation and Scattering in Random Media, Volume 1: Single Scattering and Transport Theory presents the fundamental formulations of wave propagation and scattering in random media in a unified and systematic manner, as well as useful approximation techniques applicable to a variety of different situations. The emphasis is on single scattering theory and transport theory. The reader is introduced to the fundamental concepts and useful results of the statistical wave propagation theory. This volume is comprised of 13 chapters, organized around three themes: waves in random scatterers, waves in random continua, and rough surface scattering. The first part deals with the scattering and propagation of waves in a tenuous distribution of scatterers, using the single scattering theory and its slight extension to explain the fundamentals of wave fluctuations in random media without undue mathematical complexities. Many practical problems of wave propagation and scattering in the atmosphere, oceans, and other random media are discussed. The second part examines transport theory, also known as the theory of radiative transfer, and includes chapters on wave propagation in random particles, isotropic scattering, and the plane-parallel problem. This monograph is intended for engineers and scientists interested in optical, acoustic, and microwave propagation and scattering in atmospheres, oceans, and biological media.
