Newell W. Johnson,Hemantha K. Amarasingheded to include any region within which one-dimensional propagation of electromagnetic waves can occur. It is the purpose of this chapter to establish the theory of simple waveguides, expressed in the general transmission line nomenclature sketched in Chap. 5.
