ABSTRACT:
A microwave cooking container comprising a conductive layer to which is bonded a layer of material having high hysteresis loss at microwave frequencies. When subjected to microwave radiation the hysteresis loss material heats to its Curie point where its loss is substantially reduced while the dielectric loss is minimized by being effectively shielded by its proximity to the surface of the conductive layer. The conductive layer may be a metal dish cover whose outer surface supports a plastic bonded ferrite and whose inner surface contacts a food body in a metal dish. The Curie point region of the ferrite is lower than the degradation temperature of the plastic. Overlapping the walls of the dish and cover forms a microwave seal to prevent microwave heating of the dish contents.
