With successful demonstration of the 'proof-of-principle' experiment of the cusptron, the configuration of the cusptron waveguide gains importance. Although the dispersion relation for the cusptron rf circuit has been derived and experimentally verified before, the detailed properties of its dispersion characteristics are not well understood. In this paper, we will examine various aspects of the dispersion properties in conjunction with the design process of the cusptron tubes. In particular, two unique properties of the cusptron rf circuit, the mixture and the specific grouping of the azimuthal mode numbers are closely examined and demonstrated with simple physics. Special emphases are on the identification and designation of the modes, the profiles of various field components, the spectral distribution with respect to azimuthal mode numbers, and their relation to the cusptron microwave tube design
