摘要: Woveguide mode converters aro used in the 60 GHz, 200 KW plasma heating system for Doublet III both to convert from TE02 more convenient. TE01 transmission and TE11mode produce a linear polarization at antenna. Both line periodic wall porturbations, former having circularly symmetric perturbations latter curvature (m = 1) perturbations. The converter shows conversion efficiency of least 95% (99% predicted) while TE11 convertor has 90% (92% predicted). frequency sensitivity these devices will be discussed.
