Abstract
An electromagnetic oven supplies differing quantities of electromagnetic heating energy to a variety of load items or the like all of which are located within the oven cavity. In one embodiment, a food bearing tray has a first region substantially shielded from the electromagnetic heating energy by means of a conductive shield which cooperates with a shaped interior wall of the oven to provide a desired nonuniform distribution of electromagnetic energy over those regions of the tray which are not shielded. A much higher energy concentration is developed, for example, at a region near a distended wall so that a food item located in that region is heated to a higher temperature than other food items upon the tray and in other regions.
