Abstract :
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: ω=ωh=(ω2ce +ωpe2)½. It has been found that some calculations given in published papers should be checked and corrected. It shows that the p2=0 curve in the p1 2, p22 diagram, for example, has only one line rather than two lines and there is no so called anisotropic waves dispersion curve HE1. 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
