Relativistic magnetron with diffraction output, also known as magnetron with axial extraction, is a favorite in exploring the most compact narrow band high power microwave source. For further improving power conversion efficiency and radiation pattern without diminishing the compactness, this paper proposed an efficient mode conversion configuration in an S-band pi-mode operating relativistic magnetron with diffraction output. The whole device has a total length of 290 mm and a maximum diameter of 260 mm. In three-dimensional particle-in-cell (PIC) simulation, an optimized outcome that the power conversion efficiency can reach 43% corresponding to 4.2 GW output and the radiation pattern is similar to TE11 mode is achieved.
