Gives accurate dispersion equations and shows that dispersion characters of wave propagation in partially plasma filled waveguide are quite different with that in completely plasma filled waveguide, and the dispersion curves of all waves can not pass across the critical frequency line: /spl omega/=/spl omega//sub h/=(/spl omega//sup 2//sub ce/+/spl omega//sub pe//sup 2/)/sup 1/2 /. It has been found that some calculations given in published papers should be checked and corrected. It shows that the p/sub 2/=0 curve in the p/sub 1//sup 2/, p/sub 2//sup 2/ diagram, for example, has only one line rather than two lines and there is no so called anisotropic waves dispersion curve HE/sub 1/. A new kind of wave which is unknown in published papers has been found, the unusual dispersion characteristics of this kind of wave are discussed. Hence there are two kinds of waves, electromagnetic waves and waves containing quasi-static parts.
