Abstract
A susceptor for use in the heating of a foodstuff or other material in a microwave oven is constructed to have at least two regions (12,14) which are each adapted to couple with and absorb microwave energy for the generation of heat in such regions, which heat is then radiatively and conductively transferred to the material. The invention is characterized by one such region (12) having a different lossiness from the other (14), the regions being contiguous with each other. They preferably have a stepwise discontinuity of lossiness between them, which causes higher order mode or modes of microwave energy to be generated or accentuated. The susceptor may be a separate panel or may be a wall component, e.g. the bottom, of a container or utensil, or a removable cover therfor.
