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 in either a substantially vertical position or a substantially horizontal position, a first hollow waveguide secured to the launcher, a first source of microwave energy at a predetermined operating frequency secured to the first waveguide, a second hollow waveguide secured to the launcher substantially perpendicular to the first waveguide, and a second source of microwave energy at a predetermined operating frequency secured to the second waveguide. Alternatively, a single waveguide is secured to the cylindrical launcher and has only a single source of microwave energy secured thereto. In either case, a mode stirrer can be installed within the cylindrical microwave launcher.
