摘要：

A Denisov launcher operating at 420 GHz with TE17,4 mode is designed and optimized through theoretical analysis and numerical simulations. The launcher consists of a mode converted waveguide and a helical cut. Instead of using the conventional perturbations, a sinusoid type perturbation is used in this converted waveguide. Operations of the launcher are analyzed by the coupled mode theory. The field at the output aperture of the launcher has a nice Gaussian profile distribution. The conversion efficiency is more than 98.1 %. The parasitic modes in the launcher and the aperture field profile were analyzed. The wall field of the launcher is analyzed in case that the input wave is rotating left-hand. A full 3D electromagnetic field analysis of the integrated launcher has been done. The results are in good agreement with the numerical calculation results.
