    摘要： 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.

    摘要： A reusable self-supporting field director for use in heating an article in a microwave oven is characterized by a plurality of vanes, with each vane extending radially outwardly from a central axis.Each vane is angularly adjacent to two other vanes and is attached to each other at their inner ends. Each vane has a predetermined thickness dimension.Each vane each vane has a substrate formed from an electrically non-conductive material having a predetermined coefficient of thermal expansion, and an electrically conductive sheath having a predetermined coefficient of thermal expansion that is different from the coefficient of thermal expansion of the substrate. The sheath encases the substrate so that a portion of the first and second major surfaces and a portion of the first and second minor surfaces of each vane are covered by an electrically conductive material. The sheath and the substrate are arranged in a laterally symmetric fashion so that thermal expansion effects due to heating are equalized across the thickness of each vane.
