Abstract
A susceptor for use in microwave heating and a method of manufacturing a susceptor for use in microwave heating are shown to include a substrate and a coating of electrically conductive particles applied to the substrate in a pattern that results in a distribution of microwave energy across the pattern so that burning or charring of the substrate is substantially prevented. The coating is an ink coating and the ink coating is applied to the substrate in a printing operation. The pattern is shown to include a plurality of subpatterns located within an effective heating area wherein the positioning of subpatterns is sufficient to radiate the desired heat without burning.
