A method for constructing a door for microwave ovens has an inner frame forming a quarter wavelength pocket around the opening and a smaller gap to the housing

摘要

The door (2) closes the inner chamber (1) ensuring that any gap (5) is less than a quarter wavelength in dimension and the inner part (9) forms a section (4) (lambda /4 pocket) around the opening edges. A thermally resistant and radiation transparent glass panel (6) is held by adhesive (7).
