This chapter is a continuation of Chapter 10 and devoted to discuss the waveguides of a circular cross-section. The general formulations for the metallic waveguides that are presented in Chapter 10, will be applied in this chapter to analyze the behavior of electromagnetic waves and power flow in the metallic waveguide of circular cross-section. The topics of the chapter are analyzed in details and supported by numerous illustrative examples and figures in addition to solved problems. Homework problems are included at the end of the chapter.
Keywords: Attenuation constant, cut-off frequency, cut-off wavelength, dominant mode, group velocity, phase constant, phase velocity, power loss, Poynting vector, propagation constant, wave impedance.
