The complex transmission coefficients, their representations on the SMITH CHART, and their uses form the subject of Chap. 7, including the graphical determination therefrom of bandwidth and Q of resonant and antiresonant line sections. Several uses of expanded portions of the chart coordinates are described in Chap. 6 an explanation is given of equivalent circuit representations of impedance and admittance on the chart coordinates. Chapters 4 and 5 describe the radial and peripheral scales of this chart, which show, respectively, the magnitudes and angles of various linear and complex parameters which are related to the impedance coordinates of the chart. 2 and 3 by an explanation of how these concepts are related to their quantitative representation on the "normalized" impedance coordinates of the SMITH CHART. Qualitative concepts of the way in which electromagnetic waves are propagated along conductors are given in Chap. The Introduction to this book relates some of the modifications of the basic SMITH CHART coordinates which have taken place since its inception in the early 1930s.
It also describes the construction of boundaries, loci, and forbidden regions, which reveal overall capabilities and limitations of proposed circuits and guided-wave systems. In general, the book describes the mechanics of these charts in relation to the guided-wave and circuit theory and, with examples, their practical uses in waveguide, circuit, and component applications. T he purpose of this book is to provide the student, the laboratory technician, and the engineer with a comprehensive and practical source volume on SMITH CHARTS and their related overlays.
