95GHz TE03模回旋管内置渐变波导设计
Design of built-in tapered waveguide of 95 GHz TE03 gyrotron
摘要
Abstract
The design method of high-order tapered waveguides is presented according to the mode coupling theory, and the built-in, TE03 mode, modified Dolph-Chebychev tapered waveguide of 95 GHz gyrotron is studied. Reliable optimal geometric parameters are obtained with a self-developed mathematical programme. The tapered waveguide of 95 GHz gyrotron designed is compact. Its parasitic-mode-suppression is 30 dB, which is verified by electromagnetic field simulation and meeting the design requirement. The burned pattern measured at output of the waveguide indicates good expected inner radius change of the gyrotron. The results show that the method can efficiently guide the design of high-order overmode tapered waveguide.关键词
