Abstract

An arrangement for microwave or RF hyperthermia or for other microwave heating includes a source of microwave or RF radiation directed towards the substance to be heated. Interposed between the source and the substance is a lens in the shape of a portion of a cylinder or sphere. The lens has a dielectric constant greater than about 6 at the microwave or RF frequency to provide a focusing effect. The lens is located with the focus at the location to be heated. The lens can be solid or liquid-filled. The liquid can be deionized water.
