  • In this paper, a multi-waveguide output structure for gyrotron applications is proposed. Numerical simulations are performed for this structure by using High Frequency Structure Simulator ( Ansoft HFSS ). The results show that the energy conversion efficiency of more than 95.9% from the TE01○ mode to the TE10□ mode can be reached with the bandwidth of about 3% at VSWR of less than1.5 for the TE01○ mode input.
