Electromagnetic and Circuit Modelling of Multiconductor Transmission Lines

Multiconductor transmission lines form the basic building blocks of microwave and millimetre-wave integrated circuits, and are omnipresent in digital systems. The early chapters of this book give a detailed account of the way in which self-consistent CAD circuit models for such coupled lines, carrying either TEM or hybrid modes, can be obtained from a full-wave solution of Maxwell's equations. Most of the knowledge in the field is covered, including the latest advances for lossy lines. Subsequent chapters discuss the full-wave integral equation solution for basic transmission structures on MMICs, PCBs, and Multiwire (R) and Microwire (R) boards with the method of moments. For thin coupled microstrips and striplines the proposed space domain solution offers an alternative for the classical spectral domain approach. This book is the first to handle the full-wave analysis of discrete wire structures and of lossy polygonal conductors. The modal propogation constants and all (coupling) impedances necessary to construct a circuit model are determined.
