  • Patent number: 11419190
    Abstract: A thermal increase system may include re-radiators disposed in a cavity for containing a load. Microwave energy may be generated by one or more microwave generation modules, and directed toward the cavity during operation of the thermal increase system, thereby creating an electromagnetic field in the cavity. A system controller may control switches coupled between the re-radiators and corresponding ground nodes to selectively activate and de-activate the re-radiators. The system controller may control a switch coupled between a pair of re-radiators to re-distribute the electromagnetic field in the cavity. A phase shifter may be disposed between a pair of re-radiators, which may provide a phase shift to energy passed between the re-radiators. The phase shifter may be a variable shifter that applies a variable phase shift to the energy according to commands received from the system controller.

  • Patent number: 11407576
    Abstract: A microwave packaging material including a plurality of susceptors is disclosed. Each susceptor includes a plastic film or polymer with a metal layer on one surface of the plastic film and a paper adhered to the plastic film opposite the metal layer. A patterned adhesive is bonded between a first susceptor layer and a second susceptor layer in a pattern bond creating sealed air pockets. A paper board substrate is adhered using an adhesive in a bond pattern to one of the susceptor layers facing the metal of the respective susceptor layer to provide the microwave packing material rigidity. Upon exposure to microwave energy in a microwave oven, moisture is trapped between the paper board substrate and the susceptor layer creating a vapor pressure that causes the sealed air pockets to form expanded air pockets.
