Patent ID: 8217324

Claim:
A susceptor assembly for use in a microwave oven, the susceptor assembly comprising: a generally planar susceptor including an uninterrupted electrically lossy layer, the electrically lossy layer defining a generally planar presentation surface able to accept an article for presentation to the resonant cavity of a microwave oven, the susceptor having a second generally planar opposed surface; at least one vane having a connection edge and a single free edge thereon, the vane being mechanically connected along its connection edge to the opposed surface of the susceptor such that substantially the entire length of the vane is overlaid by the opposed surface of the susceptor, the vane having a surface thereon, at least a portion of the surface of the vane being electrically conductive, the connection edge of the vane and the planar susceptor intersecting along a line of intersection, the line of intersection extending in a generally transverse direction with respect to the planar susceptor, the electrically conductive portion of the vane being disposed no farther than a predetermined close distance from the electrically lossy layer of the planar susceptor, so that in the presence of a standing electromagnetic wave 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, attenuation of the electric field component of the electromagnetic wave in the plane tangent to the surface of the vane resulting in enhancement of the components of the electric field in the planar susceptor.
