ABSTRACT:
A rectangular waveguide energized in the TE.sub.10 mode is externally provided on at least one of its major surfaces with one or more pairs of ferrite cores rising from that surface on opposite sides of its electric plane, an end face of each ferrite core being aligned with an aperture in the guide surface whereby two counterrotating magnetic fields in the interior of the guide induce corresponding fields in the two cores. The induced magnetic fields travel outward in the cores and are reflected at their remote ends for return to the guide with a phase shift controlled by a unipolar biasing current traversing a pair of coils which are respectively wound about these cores to generate two mutually opposite magnetic fields therein. The cores and their coils may be spacedly surrounded by an enclosure for the forced circulation of a cooling fluid therearound.
