Circuits for guided waves - Theory, realizations, and applications
Abstract
The book sets forth the important analytical tools for realization and design of the principle types of circuits for guided microwaves. The concepts of normalization, reference fields, and equivalent lines are examined, and general theory of multipoles is formulated, defining their various characteristic matrices. Besides the transmission matrix, attention is also given to the impedance and admittance matrices, in order to render exact the notion of equivalent circuits. This then permits application of known methods of classical electrical network theory to waveguide circuits. These theoretical considerations serve as the basis for the core of the work, the analysis of multipoles, from two-terminal to eight-terminal networks. Their fundamental properties and chief applications are investigated. Concerning hexapoles, detailed study is given to simple tees and Y-junctions, was well as to nonreciprocal networks. Chapters are devoted to the hybrid tee and the magic tee eight-terminal networks. A final chapter considers design of a bandpass filter, measurements with impedance bridges, measurements of reflection coefficient moduli, and design of some junctions.
