| Abstract: | The interaction between the plasma and electromagnetic wave is a focus of the study of high-power microwave devices. By way of loading plasma, the output power and efficiency of a microwave device can be immensely enhanced. Through the loading of the periodic slow-wave structure in a cylindrical circular waveguide that is filled with a periodically magnetized plasma, the propagation properties of the electromagnetic wave along such a media was subjected to examination. Based on strict theoretical deduction, the dispersion equations were derived, and the numerical calculation, and analysis were done as well. |
