Abstract
A microwave oven includes a housing and a door. The housing defines an internal cavity. The door is movably secured to the housing. The door has a glass pane and a mesh sheet. The mesh sheet is secured to an internal surface of the glass pane and is exposed along an interior side of the door. The housing and mesh sheet collectively form a faraday cage when the door is in a closed position.
