Patent ID: 8629380

Claim:
A thermally insulated susceptor structure comprising: a dimensionally stable base having a first side and a second side opposite the first side, the base including a plurality of corrugations; a first susceptor overlying the first side of the base in a substantially planar configuration, so that a plurality of insulating voids are positioned between the first susceptor and the plurality of corrugations; and a second susceptor overlying the first susceptor in a substantially planar configuration, wherein the first susceptor and the second susceptor each comprise microwave energy interactive material, and at least one of the first susceptor and the second susceptor circumscribes at least one microwave energy transparent area, wherein the at least one microwave energy transparent area comprises the microwave energy interactive material in a deactivated condition, wherein the at least one microwave energy transparent area comprises a first plurality of microwave energy transparent areas arranged around a center of the construct, and a second plurality of microwave energy transparent areas arranged around the first plurality of microwave energy transparent areas, wherein the first plurality of microwave energy transparent areas decrease in number from the center of the construct towards the second plurality of microwave energy transparent areas.
