Abstract:

Research was continued to advance the state of the art in the field of passive type millimeter wave transmission line components applicable for current and future systems in the millimeter wave range extending from approximately 30 to 100 kmc 10 to 3 mm wavelength. Measurements on H-guide were made to determine 1 the performance characteristics of newly fabricated shaped mode launchers, 2 the effect of flange separation on transmission characteristics, and 3 the effect of an angular separation between launching horn and H-guide. Also reported is a later series of measurements on H-guide mode launchers using a termination in H-guide specially designed to absorb a number of modes. Three devices proposed for impedance and V.S.W.R. measurements in H-guide are described. Further investigation is reported in the analysis of the scattering matrix of lossless single mode and multimode regions containing small ferrite bodies. Also described is an analysis applied to a ferrite ellipsoid in a single mode rectangular guide using a small obstacle technique. Author
