A virtual cathode oscillator (VCO) with an axially extracted TE10 mode of rectangular waveguide is investigated by PIC simulation which emits microwaves axially through an antenna without mode converter or transition waveguide, making the system more simple and compact. A microwave power of 500 MW is obtained with an electron beam of 400 keV and 8.9 kA, which can be obtained experimentally from the TomaChan accelerator. The beam-to-microwave efficiency is 14%. The frequency and mode of the generated microwave are very pure. These results can provide a possible method for building a compact high-power microwave device.
