Abstract
A microwave laminate for heating, browning, and crisping food products is provided. The microwave-absorbing region of the laminate is formed from electrically conducting film of shielding thickness. The film is patterned to provide an increased effective electrical sheet resistance that allows the susceptor to substantially absorb rather than reflect microwave energy. Also, a microwave susceptor underlay or shield formed from a patterned electrically conducting film of shielding thickness is provided for controlling temperature gradients within microwave susceptors.
