1. An electromagnetic power divider/combiner comprising:

  • a waveguide having a major axis and a circular cross section orthogonal to said major axis;

    a first input port and a first output port, said first input port and said first output port both disposed near a first end of said waveguide, said first input port being operative to couple a vertically polarized electromagnetic wave to said waveguide and said first output port being operative to couple said vertically polarized electromagnetic wave from said waveguide;

    a second input port and a second output port said second input port and said second input port both disposed near said first end of said waveguide, said second input port being operative to couple a horizontally polarized electromagnetic wave to said waveguide and said second output port being operative to couple said horizontally polarized electromagnetic wave from said waveguide;

    a slow-wave structure comprising a series of fins oriented transversely of said major axis of said waveguide and being spaced apart along said major axis of said waveguide; and

    a short circuit disposed at a second end of said waveguide opposite said first end of said waveguide for reflecting said vertically polarized electromagnetic wave and said horizontally polarized electromagnetic wave.
