Abstract
A rectangular microwave resonant cavity applicator comprising two spaced-apart, cavity-containing sections is disclosed for heating a product web. Each section has a planar peripheral lip which faces the other and the sections are spaced apart by a distance 'd'. The lips have arrays of ferrite segments mounted on their surfaces which serve to limit radiation of microwave energy from the open space between the sections, through which the product web passes.
