Abstract
A microwave apparatus (10) with conductive fingers (104, 105) on extensions (101, 102) contacting the material (200) to be processed and knife edges (100) adjacent the material on opposed sides of the cavity (12). The fingers and knife edges prevent leakage of the microwaves from the cavity (12) through extensions (101 and 102) and can be replaced or modified for various material 200 and die cross-sections. The apparatus is particularly useful for curing electrically conductive resin impregnated fibers.
