A millimeter wave sheet-beam extended interaction oscillator (SBEIO) operating at TM_(31) is studied. The dispersion characteristic and coupling impedance of the slow-wave structure are analyzed and the slow-wave structure for 8 mm SBEIO is designed with CST code. With the simulation of the PIC software, CHPIC code, when the SBEIO operates at TM_(31) at 2π point with the beam voltage 19kV, current 3 A, and longitudinal magnetic field 0.3 T, the operating frequency is 37.9 GHz and the output power is over 3.5 kW. The simulation results agree well with the design values.
