Abstract
A microwave oven excitation system comprising a cylindrical microwave launcher for radiating microwave energy into a heating cavity of a microwave oven which is mounted adjacent to the heating cavity, a quarter-wave matching waveguide secured to the launcher, a rectangular waveguide secured to the quarter-wave matching waveguide, and a source of microwave energy at a predetermined operating frequency secured to the rectangular waveguide remotely from the launcher. In addition, a mode stirrer may be optionally installed within the cylindrical microwave launcher. Also, an iris may be optionally mounted between the cylindrical microwave launcher and the heating cavity.
