Title: Microwave heating apparatus with multiple coupling elements and microwave power sources

Abstract: A cut off conductive enclosure tube supports a plurality of wire-like energy coupling elements partially wrapped about a centrally located dielectric support tube for receiving a frankfurter or other material body. Each coupling element is excited by an independent low power source of microwave energy, the energy coupled to different regions of the body being absorbed thereby to provide isolation between coupling elements and sources. Continuous processing operations are possible, and a rectangular configuration and industrial heating applications are described.
