摘要：
A novel configuration of vireator with coaxial waveguide generated by annular electron beam under low guiding magnetic field is presented and the 2. 5-D particle-in-cell simulations are carried out using KARAT code. We obtain High power microwave with average power of 2. 7GW, frequency of 3. 8GHz, of which the beam-to-wave power efficiency and dominant mode are 12 % and TEM mode, respectively.
