PROPAGATION PROPERTIES OF OVERMODED PLASMA CIRCULAR WAVE-GUIDE

The normal modes in overmoded plasma waveguide coated with a lossy mat erial are analyzed, particularly for the variation of its propagation properties with plasma parameters, coating materials, dimensions of th e waveguide and frequencies. The separate characteristic equations of normal modes are derived, and their relevant approximate solutions are given. The limit results are consistent with those given in literatur e. The analysis shows that the propagation properties of the overmoded plasma circular waveguide can be controlled by choosing proper plasma parameters, coating materials and waveguide dimensions.
