Abstract: A field director assembly includes electrically conductive vanes configured to prevent arcing in an unloaded microwave oven.

Abstract: A susceptor assembly comprises a generally planar susceptor having an electric field director structure mechanically connected thereto. The field director structure includes at least one, but more preferably, a plurality of two or more vanes mechanically connected to the susceptor. Each vane has a surface at least a portion of which is electrically conductive. The vane(s) are most preferably disposed substantially orthogonal to the planar susceptor. The connection may be either a fixed or a flexible articulating connection. In use, such as in the presence of a standing electromagnetic wave generated within a microwave oven, only an attenuated electric field component of the electromagnetic wave exists in a plane tangent to the surface of the vane in the vicinity of the conductive portion of the vane.

Abstract: A susceptor assembly includes electrically conductive vanes positioned with respect to each other and to an planar susceptor member having an electrically lossy layer thereon to prevent overheating of the susceptor in an unloaded microwave oven.

Abstract: A field director assembly includes electrically conductive vanes positioned with respect to each other and to a planar support member to prevent overheating of the susceptor in an unloaded microwave oven.

Abstract: This invention relates to a high temperature microwave susceptor structure comprising a microwave interactive material of carbon with a naturally occurring polymer or derivative and a base layer of a high temperature paper.

Abstract: The present invention is directed to a method of heating a food, comprising the step of imparting microwave energy to a food wherein a portion of the microwave energy is converted to heat by use of a coating derived from an ink comprising natural polymer binder, substantially non-aggregated particulate nonmetallic microwave susceptor material, an aqueous solvent for the natural polymer binder, and, optionally, a chemical dispersing aid. The food is heated, and preferably browned, without the occurrence of electrical arcs that would burn the food or damage the oven.
