摘要
Transmission and reflection coefficients of hybrid modes in thc 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 thc sliding waveguide which is composed of th corrugated waveguide with 88.9 mm phi and the smooth-wall waveguide with 110 mm phi. At the sliding length near multi-half-wavelength in vacuum, transmission and reflection powers in the sliding waveguide change slightly, because the very sm;lll amount of standing wave in high higher-mode is produced resonantly in the gap.
