A new type of coupled cavity interaction circuit for harmonic multiplying gyrotron amplifier applications is proposed. Based on Ansoft HFSS software, the relation of the conversion coefficient from the rectangular waveguide TE□10 mode to the cylindrical waveguide TE○01 mode with geomitric parameters and frequency is calculated and analyzed, and the effect of the geomitric structure of the cavity on mode selection and suppression is discussed. Simulating results show that the energy conversion efficiency of more than 97% from the TE□10 mode to the TE○01 mode can be reached, and 3dB bandwidth is not less than 327MHz. The coupled cavity can be used as an input structure for harmonic multiplying gyrotron amplifier applications
