Abstract
Apparatus for heating with microwave energy is disclosed comprising a plurality of spaced microwave elements in a flexible webbing adapted to fit the contour of any object to be cooked. The microwave elements, such as cups, have a height of substantially one-quarter of a wavelength. An intense fringing electric field pattern results with the electric field being 180.degree. out of phase in close proximity to the open ends of the elements. The material contacted by these ends will be suitably browned or seared. An impedance matching dielectric member may also be provided in contact with the apparatus.
