CHOKES FOR MICROWAVE DRYERS THAT BLOCK MICROWAVE ENERGY AND ENHANCE THERMAL RADIATION

摘要

Systems and methods are provided for chokes for microwave radiation. One embodiment is an apparatus that includes a choke assembly. The assembly includes a first choke plate, and a second choke plate. The assembly also includes a first layer disposed at a surface of the first choke plate. The first layer includes a material that attenuates microwave radiation via dielectric heating by converting the microwave radiation into heat, and a substance, disposed between the material of the first layer and the gap, that is transparent to the microwave radiation. The assembly further includes a second layer disposed at a surface of the second choke plate that faces the first layer. The second layer comprises the material that attenuates the microwave radiation via dielectric heating by converting the microwave radiation into heat, and the substance, disposed between the material of the second layer and the gap.
