Abstract
Input and output waveguides are each formed from an inner tubular conductor coaxially disposed within an outer tubular conductor. The proximal ends of the waveguides are coupled through relatively rotatable sleeves of a coupling assembly that maintains the waveguides coaxial with a central axis. The field strength of a wave at the distal end of the input waveguide defines two cycles of a sinusoid about the axis. The inner conductors each carry on their outer surface an equal number of evenly spaced ridges. The ridges in the input waveguide cause the field strength to be invariant at the proximal ends. The ridges in the output waveguide cause the field strength to define the two cycles of the sinusoid at the distal end of the output waveguide.
