Cylindrical Hollow Metallic Waveguides and Cavity Resonators
This chapter contains solutions and calculations for circular cylindrical hollow metallic waveguides and cavity resonators. Here the solutions of Helmholtz’s equations in cylindrical coordinates are presented, Bessel functions’ and their first derivatives’ properties are discussed in detail. Other items explored in this chapter include EM characteristics of TE and TM modes, explanation of mode indexes, dispersion characteristics, and cutoff frequencies. There is also a schematic sectional view of TE11, TM01, TE111, TM011 modes in waveguides and resonators.
