We have studied by numerical simulation, a new three-stage configuration of the inverted gyrotwystron, which operates with harmonic-multiplying mechanism. The simulations based on the analytical theory predicts a highly efficient and high-phase stability operation of the device, and gives results consistent with those measured in experiment. Related investigations of electron bunching, output power-frequency response, drive-gain dependence, and phase fluctuations due to beam voltage rippling are also presented.
