Resonators Cavity Resonators Transmission Line Model The simplest cavity resonator is formed by using a transmission line. The source end can be terminated by Z S and the load end can be terminated by Z L. When Z S and Z L are non-dissipative, such as when they are reactive loads, then no energy is dissipitated as a wave is re ected o them. Therefore, if the wave can bounce.

In our discussion of transmission lines, we pointed out that the resistance of a.Waveguides can be simply described as metal pipes. Depending on their cross section there are rectangular waveguides (described in separate tutorial) and circular waveguides, which cross section is simply a circle. This tutorial is dedicated to basic properties of circular waveguides. For properties visualisation the electromagnetic simulations in QuickWave software are used. All examples used. 3 Attenuation of Modes in Waveguides 16 1. 4 Resonating cavities 18 2. In this chapter we continue with the topic of solutions of the Maxwell equations in the form of waves. This time we seek solutions in the presence of bounding surfaces which may take a variety of forms. The basic possibilities are to have boundaries in 1. one dimension only, such as a pair of parallel planes; 2. two.
