Description
Summary:A novel relativistic magnetron (RM) with a circularly polarized TE11 coaxial waveguide mode and its corresponding mode excitation are investigated in this paper. By operating in the 4π/5 mode in the ten-cavity RM and compactly designing the RM structure with the all cavity-magnetron axial extraction technique, the RM can directly output a circularly polarized TE11 coaxial waveguide mode in a reversible direction of rotation without any mode converters. In addition, the analysis of mode excitation can be generalized to a 2N-cavity RM, where 2N  >  4 is the number of cavities. Results of the 3D particle-in-cell (PIC) simulation show that a high power microwave (HPM) with an operating frequency of 4.15 GHz and an output power of 700 MW is obtained from the RM, corresponding to the power conversion efficiency of 50.0%.
