High frequency electromagnetic waves in a bounded, magnetized and warm plasma

The electromagnetic waves in a uniform, magnetized plasma, bounded by a cylindrical waveguide are studied using warm plasma theory. In the case of a cold plasma, backward electromagnetic waves are obtained which exhibit the phenomenon of Faraday rotation, in contrast to the Trivelpiece and Gould electrostatic modes which do not show this characteristic. Numerical results are presented for the linear LISA machine. A generalization of the Ghosh and Pal dispersion relation for a warm, magnetized plasma is derived. (author)
