Abstract
A modified H guide has been proposed as a low-loss low-mode waveguide for the submillimetre-wave region, and is supported by theoretical studies and microwave model measurements. A resonance technique using guide-length variation with temperature change for attenuation and mode-characteristic measurement is shown to be feasible at 890 GHz with an HCN laser. Guide attenuations less than 8 dB/m are obtained in initial measurements on a submillimetre waveguide.
