Abstract

For a cylindrical wave guide, filled with hot collisional and moving plasma, the expression for damping coefficientK i (imaginary part of the wave vector) has been derived and discussed in case of TM modes. It is observed that due to the effects of ion collisions,K i remains less than zero for all values of β(=ν/c) and waves suffer strong reflections for β≤0.5. The damping is however not affected for moderate changes in collision frequencies, while for low values of electron collision frequency and plasma density, the damping coefficient varies in a parabolic fashion with sharp reflections at β≅0.3.
