ABSTRACT
This chapter examines the following conductor-set cross sections, each involving at least two electrically separated conductors: the circularly symmetrical coaxial line; the circular-wire parallel pair in space; one wire above a highly conducting infinite plane; a cable consisting of a circular outer conductor and an inner conductor which is offset from the center of the outer one; and the circular-wire parallel pair with a highly conducting cylindrical shield. It analyses the basic electromagnetic behavior in uniform sections of lines and waveguides with geometrically simple cross sections. The chapter considers two topics that illustrate the application of field-propagation and boundary-condition concepts: braided conductors—the effects of using a braided outer conductor on a coaxial cable or of using a braided shield—and conductor-support techniques—the effects caused by various structures that support the conductors of a line and to maintain the correct spacing.
