New. <p>Improvements in the accuracy, computational cost, and reliability of computational techniques for high-frequency electromagnetics (including antennas, microwave devices and radar scattering applications) can be achieved through the use of 'high-order' techniques. This book outlines these techniques by presenting high-order basis functions, explaining their use, and illustrating their performance. The specific basis functions under consideration were developed by the authors, and include scalar and vector functions for use with equations such as the vector Helmholtz equation and the electric field integral equation.</p> <p>The book starts by considering the approximation of scalar functions, and explores the error in some of those representations. Singular functions (those that are unbounded) are also considered, since these often arise in practical EM problems. The authors then discuss the approximation of vector functions, and summarize the various classes of vector basis functions that have been used by the professional community. Following this, they present higher-order basis functions for the most common cell shapes used in finite element analysis procedures. Finally, they consider some of the implementation details associated with the use of these functions for integral equation/method of moments formulations and differential equation/finite element method approaches.</p> <p>This book provides an essential introduction to these techniques for researchers, graduate students and practicing professionals in the discipline of computational electromagnetics.</p>, 6, New. This book integrates analytical and digital solutions through Alternative Transients Program (ATP) software, recognized for its use all over the world in academia and in the electric power industry, utilizing a didactic approach appropriate for graduate students and industry professionals alike. This book presents an approach to solving singular-function differential equations representing the transient and steady-state dynamics of a circuit in a structured manner, and without the need for physical reasoning to set initial conditions to zero plus (0+). It also provides, for each problem presented, the exact analytical solution as well as the corresponding digital solution through a computer program based on the Electromagnetics Transients Program (EMTP). Of interest to undergraduate and graduate students, as well as industry practitioners, this book fills the gap between classic works in the field of electrical circuits and more advanced works in the field of transients in electrical power systems, facilitating a full understanding of digital and analytical modeling and solution of transients in basic circuits., 6, Berlin-Heidelberg: Springer-Verlag, 1978. Classic text presents a series of lectures dealing with applied inverse problems in a variety of fields. Topics covered include ray theoretical inverse problems in geophysics; linear inverse theory; analytical extrapolations and inverse problems; regularization of linear inverse problems in Fourier optics; inversion-like integral equations; spectral transform and nonlinear evolution equations; inverse problem for electromagnetic prospection; inverse problem for finite range potentials; Gel'fand-Levitan theory of the inverse problem for singular potentials; etc. Text in English and French. 425 pgs. Illustrated. Small stamp on lower title page and rear endpaper; clean pocket remnant on rear endpaper; reference numerals on lower front cover. Minimal shelfwear.. First Edition. Soft Cover. Very Good. 8vo - over 7¾" - 9¾" tall., Springer-Verlag, 1978, 3<
