Download E-books Electromagnetic Theory and Computation: A Topological Approach (Mathematical Sciences Research Institute Publications) PDF

By Paul W. Gross

Even though topology was once famous by means of Gauss and Maxwell to play a pivotal function within the formula of electromagnetic boundary worth difficulties, it's a principally unexploited instrument for box computation. the advance of algebraic topology in view that Maxwell presents a framework for linking information constructions, algorithms, and computation to topological features of third-dimensional electromagnetic boundary price difficulties. This publication makes an attempt to reveal the hyperlink among Maxwell and a contemporary method of algorithms. the 1st chapters lay out the suitable proof approximately homology and cohomology, stressing their interpretations in electromagnetism. those topological buildings are consequently tied to variational formulations in electromagnetics, the finite aspect procedure, algorithms, and sure features of numerical linear algebra. A routine subject matter is the formula of and algorithms for the matter of constructing department cuts for computing magnetic scalar potentials and eddy currents. Appendices bridge the space among the fabric provided and conventional expositions of differential types, Hodge decompositions, and instruments for understanding representatives of homology sessions as embedded manifolds.

Download E-books Theory of Electromagnetic Wave Propagation (Dover Books on Physics) PDF

By Charles Herach Papas

While there are such a lot of books on common electromagnetic thought for graduate-level scholars, there are considerably fewer that focus on the radiation points as does this famous paintings. Interfacing physics and electric engineering, Dr. Papas's in actual fact written textual content discusses hugely very important themes within the concept of electromagnetic wave propagation and antennas in a fashion that finds the inherent simplicity of the elemental rules and their logical improvement from the Maxwell box equation.
Chapter 1: Maxwell's box equations and people components of electromagnetic box thought worthy for knowing the rest of the book.
Chapter 2: How the dyadic Green's functionality can be utilized to compute radiation from monochromatic sources.
Chapter three: difficulties of radiation emitted by way of twine antennas and antenna arrays from the point of view of research and synthesis.
Chapter four: equipment of increasing a radiation box in multiples — one in line with the Taylor enlargement of the Helmholtz integrals and the opposite, on all enlargement in round waves.
Chapter five: Wave features of radio-astronomical antenna theory.
Chapter 6: thought of electromagnetic wave propagation in a plasma medium describing the habit of an antenna immersed in this sort of medium.
Chapter 7: Covariance of Maxwell's equations in fabric media and its program to phenomena resembling the Doppler effect.
By unifying quite a few subject matters below the only mantle of electromagnetic concept, Professor Papas has made the contents of this publication effortless to benefit and handy to coach. additionally, the booklet assembles a lot information formerly to be had in basic terms in scattered examine literature. the result's a very good graduate-level textual content which may additionally lend itself to self-instruction by means of researchers.
