ing reflections). Because most waveguide is rectangular, however, a somewhat
more complex system is needed. Figure 5-16 shows a rotating joint consisting of two
circular waveguide sections inserted between segments of rectangular waveguide.
On each end of the joint there is a rectangular-to-circular transition section.
In Fig. 5-16, the rectangular input waveguide operates in the TE~0 mode that
