Abstract
In mm-wave systems for ECRH using the HE 11 hybrid mode, the maximum transmitted power is limited bythe strongly peaked thermal load in the vacuum barrier window. In this paper we present mode converters at140 GHz which create a mixture of HE1N hybrid modes in corrugated waveguides. Such a mode mixtureyields a more uniform power density than HE11 mode in the section where the window is placed, and aGaussian distribution at the waveguide aperture.
