Cylindrical waveguide modes
Webmodes whose cutoff frequencies are below the excitation frequency are excited (f rect f c ≤), which means that their mode indices must belong to the upper right quarter of this ellipse as shown in Fig. 2. Figure 2. Calculating the number of modes in rectangular waveguide as number of points inside quarter ellipse in (n,m) coordinate system. WebThe cylindrical waveguide, however, is bounded in two dimensions rather than one. Thus two integers, l and m, are necessary in order to specify the modes, in contrast to the …
