    Notizen: Abstract Experimental measurements by wavepacket reflectometry are carried out to verify the low transmission loss of hybrid mode on HE11 in the corrugated waveguide with 88.9 mm in diameter. The HE11 mode is injected into the 62-m straight circular corrugated waveguide and the beat between the HE11 and HE21 (including degenerated TE01 and TM02) modes is observed. The loss is too small to measure and inferred to be less than 2 db/km. The result shows that the use of HE11 mode for electron cyclotron heating system is suitable.

    Notizen: Abstract Transmission and reflection coefficients of hybrid modes in the sliding waveguide are discussed on the basis of mode matching method and multi-mode network theory. It is confirmed that the decrease in power of 〈 0.2% at 84 GHz is obtained for 2 cm in gap of the sliding waveguide which is composed of the corrugated waveguide with 88.9 mm diam. and the smooth-wall waveguide with 110 mm diam. At the sliding length near multi-half-wavelength in vacuum, transmission and reflection powers in the sliding waveguide change slightly, because the very small amount of standing wave in high higher-mode is produced resonantly in the gap.
