A basic text on the theoretical foundations of information theory, for graduate students and engineers interested in electrical communications and for others seeking a general introduction to the field, with some important new material on tilting probability distributions and coding for discrete channels.

A set of tables of spheroidal wave functions designed to simplify the computation of acoustic and electromagnetic scattering from spheroids. The tables were computed to five-place accuracy on the Whirlwind digital computer, and automatically tabulated. An introduction discusses the mathematical properties of the functions and describes some of their applications.


This book develops a consistent macroscopic theory of electromagnetism and discusses the relation between circuit theory and field theory. The theory is developed in successive steps from the Lorentz force, the integral form of Maxwell's equations in free space, and suitable macroscopic models of polarized and magnetized matter.Special features* Covers the electromagnetism of moving bodies and the process of electromechanical energy conversion* Introduces a power-series technique for analyzing quasi-static fields and quasi-stationary systems* Emphasizes the synthesis of fields as opposed to the analysis of fields* Presents, in an appendix, the four-dimensional relativistic formulation of macroscopic electrodynamics recently developed by one of the authors (L. J. Chu)

This book develops a consistent macroscopic theory of electromagnetism and discusses the relation between circuit theory and filed theory. The theory is developed in successive steps from the Lorentz force, the integral form of Maxwell's equations in free space, and suitable macroscopic models of polarized and magnetized matter. It covers the electromagnetism of moving bodies and the process of electromechanical energy conversion; introduces a power-series technique for analyzing quasi-static fields and quasi-stationary systems; it emphasizes the synthesis of fields as opposed to the analysis of fields. Presented in an appendix, the reader will also find, the four-dimensional relativistic formulation of macroscopic electrodynamics.
