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 (= /c) and waves suffer strong reflections for ![beta](/content/tx1422m6v1849v0x/xxlarge946.gif) 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 ![beta](/content/tx1422m6v1849v0x/xxlarge946.gif) 0.3. |
