Propagation characteristics and guiding of a high-power microwave in plasma waveguide

The propagation characteristics of the high-power microwave guiding in the plasma waveguide was presented. It was found that the microwave pulse expands the plasma waveguide by its ponderomotive force and remains trapped with the plasma waveguide and is guided in it. The propagation structure was found to be the fundamental TE mode for the plasma channel width narrower than the cutoff wavelength. The results showed that it is possible to control the propagation mode in the plasma waveguide by changing the plasma waveguide parameters and to support the more potentiality of the applications with the laser-matter interaction.
