Abstract
A new directional coupler capable of transferring variable amounts of power (0 to 100 per cent) from one waveguide to another is described and analyzed. The coupling element in this coupler is a long slot containing a grid of wires in the common narrow wall of the two waveguides. The coupler can carry nearly the full power of the waveguide and has been used for a variable high-power divider as well as in a variable high-power attenuator. The quantitative theory presented agrees closely with the experimental results.
