Network scattering parameters are powerful tools for the analysis and design of HF and microwave networks. A review of the scattering parameters is given in this book with discussion of its applications in analysis of the stability, input and output reflection coefficients, power gains and other network parameters. The so-called generalized scattering parameters are introduced in later chapters. The aim of this book is to give a thorough working knowledge of scattering parameters and their applications in circuit analysis and design. To this end, numerous illustrative examples are given for every topic. The book should prove to be a useful companion to both students and lecturers in the field of HF and microwaves and optics, as well as practicing engineers.
