Abstract:
A method of making a self-supporting field director structure for use in heating an article in a microwave oven comprises in any operative order, the steps of folding a first and a second elongated vane blank along a central fold line to form at least two V-shaped vane doublets; inserting each of the vane doublets into a slotted annular support member so that each vane in each vane doublet extends through an adjacent slot in the annular support member; and attaching the vane doublets at their vertices to define a vane array.
