摘要：
This paper focus on the design of a quasi-optical mode converter for large power gyrotron with the operation frequency of 94GHz and the working mode of TE22,6. A quasi-optical mode converter consists of a Denisov-type radiator and two mirrors. By analysis of the working mechanism for the Denisov radiator and the calculation theory of the mirror field, the program is performed to optimize the parameters of the radiator and mirror system. Numerical calculation results show that the edge feed electric field of the output window reaches -30dB and the power transmission efficiency is 95% with the Gauss beam content of 96%. Simulation results from FEKO verify that the radiator power transmission efficiency is 92.9% and the Gauss content is 94%.
