Abstract

A novel cover (38, 40, 48) arrangement is described for use with foodstuff holding pans (30) to be heated in a microwave oven. The cover is one which in terms of microwave energy, does not transmit reflected energy. Thus, the cover acts in a manner analogous with non-reflecting coatings in optics and permits passage of the microwave radiation into the container holding the foodstuff (18), while substantially preventing escape of microwave radiation reflected from the foodstuff surface and container bottom (32). In this manner the microwave energy is retained and concentrated within the container, resulting in more efficient and uniform heating of the foodstuff. The novel cover is particularly valuable when used with aluminium foil pans, which without the cover of this invention seriously reflect microwave radiation.
