Popis:	It is pointed out that millimeter-wave vortex may contribute an efficient plasma heating since it was found that the millimeter-wave vortex can propagate in magnetized plasma even in which the normal plane wave is in cut-off condition. Then, it was assumed that the vortex field was the Laguerre-Gaussian (L-G) mode which is free-space solution, but the generation and stable propagation of the L-G mode vortex are not easy in the millimeter frequency range. On the other hand, it is known that millimeter-wave hybrid mode of cylindrical corrugated waveguide has also vortex property. In this paper, we investigate propagation characteristics of millimeter-wave vortex of a hybrid mode of cylindrical corrugated waveguide in the magnetized plasma by using three dimensional numerical simulations with finite-difference time-domain (FDTD) method.
