Abstract :
A design of a coaxial input coupler with an outer TE811 mode and inner TE021 mode for the Ka-band second harmonic gyroklystron is presented in this paper. Simulation results from three-dimensional electromagnetic code show that 91% of the total energy is stored in the inner cylindrical cavity, and a circular TE021 mode with high mode purity in an input cavity is obtained.
