| Abstract: | In this paper, the formula of power density of waveguide with annular plasma filled in finite magnetic field has been derived. In order to increase output power of high-power microwave devices, some parameters must be taken into account, such as the thickness and the density of the annular plasma. Through careful calculation, it has been found that there are great influences to the power density by the plasma density, annular plasma thickness. The influential mechanism has been analyzed by calculating the electric field distributed on the transverse direction. |
