ABSTRACT:
A container for holding material such as foodstuff to be heated in a microwave oven, including an open-topped tray and a lid for covering the tray to form a closed cavity, wherein at least one surface of the container has one or more electrically conductive plates and/or microwave-transparent apertures for generating a microwave field pattern having a higher order than that of the fundamental modes of the container, such that the field pattern so formed propagates into the contained material to thereby locally heat the material.
