In this chapter we establish the fundamental concepts of guided waves. It is perhaps the most important chapter in the book, as almost everything else will build on these concepts. This chapter includes many numerical examples and problems. The homework problems offer many opportunities to test your understanding of the concepts. Due to the transcendental nature of the eigenvalue equations, a computer with numerical analytical software is required to make the computations feasible. You are strongly advised to develop a set of standard programs that can quickly evaluate the basic waveguide parameters of a given structure, based on the material in this chapter. You will find these programs useful as we explore different types of waveguide, mode coupling, and device construction later in the text.
