Abstract
A microwave delivery system for a cooking appliance includes a toroidal waveguide and a launching zone. The launching zone has an interior metallic surface into which a microwave energy field is introduced. The microwave energy field couples with the interior metallic surface of the launching zone thus increasing the efficiency of the energy field as it enters the waveguide. Additionally, a tuning form section is provided in the waveguide which further enhances the microwave energy field, thereby creating a maximum energy node around the inside and outside of the waveguide. Insulation is provided both in the interior of the waveguide and in a central, exterior depression defined by the waveguide.
