| contents | It was demonstrated that the vortex field of a hybrid mode can propagate in the mag-netized plasma region where plane waves are unable to propagate due to the cut-off condition. In this study, the dependence of the penetrated power of injected as millime-ter-wave vortices of the hybrid mode in magnetized plasma is analyzed using the Fi-nite-Difference Time-Domain (FDTD) method. The effect of the radius size of the cor-rugated waveguide on the penetrated power is described, revealing its significant con-tribution to reducing the deviation of topological charge in the hybrid mode. Further-more, it was found that the penetrated power of the vortex field in magnetized plasma strongly depends on the topological charge l and the deviation of topological charge |
