Book excerpt: Annotation Consisting of 68 short chapters, this textbook for a two-semester course in electromagnetic field theory and radio frequency (RF) circuits covers antennas, transmission lines, and RF networks. This second edition includes as an appendix the problem solutions that were previously published as a separate item; otherwise, it is unchanged from the first, which was published in 1962.
