Abstract
A microwave oven comprises a cabinet and a door attached to the cabinet to form a food processing chamber. The door has a screen, an absorbing film, and a frame. The screen reflects microwave energy away from the absorbing film, the screen has a plurality of screen lines and a plurality of screen openings defined by the plurality of screen lines, and the screen has a screen period. The absorbing film absorbs microwave energy passing through the screen. The frame supports the screen and the absorbing film in order to form a window through the door and to maintain leakage of microwave energy through the door from the food processing chamber below a predetermined level. The frame supports the screen and the absorbing film so that the screen and the absorbing film are separated by a distance which is as least as great as the screen period, and the screen and the absorbing film are electrically attached to the frame.
