ABSTRACT:
A microwave browning plate utilizing members of a relatively low dielectric constant material is provided having a conductive coating on three sides with a load supported on the uncoated side. The induced currents in the conductive material provides for current induced in the dielectric material. An exponentially decreasing fringing electric field is provided as a standing wave adjacent to the uncoated side. A low dielectric constant material may be utilized with the conductive coating and an overall height of one-quarter of a wavelength will result in a thinner microwave plate. Means are provided for restricting the current flow to a desired mode.
