Abstract :
A groove guide having two parallel grooves may simultaneously propagate two modes with a small difference in phase constant. Experimental measurement of this difference for three groove separations at 100 GHz gives results close to theoretical predictions. The attenuation of one mode is a little less than for a guide with a single groove.
