Design of a TE₁₀ Taper Used in the LHCD Launcher for EAST

【摘要】 <正> Calculations of the TE₁₀tapered waveguide,which will be used in the 4.6 GHzlower hybrid current drive（LHCD）launcher on the EAST,are presented.The calculations areperformed in two ways,namely by directly solving the classical coupling wave equations,and byusing the simulation code of the high frequency structure simulator（HFSS）.According to thecalculations,the voltage standing wave ratio（VSWR）of the designed tapered waveguide can beless than 1.01 within a bandwidth of±100 MHz.更多还原
