Description
Summary:70 GHz slow wave propagation characteristics in a transversely magnetized partially filled ring-form solid-plasma waveguide have been studied experimentally employing n -type InSb ring at liquid nitrogen temperature as the plasma material. Obtained results were compared with those for the previously studied straight parallel-plate configuration. It is clearly shown that the surface wave resonance corresponding to the one observed in the straight plasma waveguide takes place also in the curved structure, and the propagation characteristics are quite similar to those of the straight configuration. Reduction of the resonant magnetic field is found with increasing the curvature of the waveguide.
