Abstract

Calculations of the TE 10 tapered waveguide, which will be used in the 4.6 GHz lower hybrid current drive (LHCD) launcher on the EAST, are presented. The calculations are performed in two ways, namely by directly solving the classical coupling wave equations, and by using the simulation code of the high frequency structure simulator (HFSS). According to the calculations, the voltage standing wave ratio (VSWR) of the designed tapered waveguide can be less than 1.01 within a bandwidth of ±100 MHz.
