Abstract
A door (100) for a microwave oven (200) is provided that includes: a door frame (102); a substantially transparent, glass or polymeric substrate (10) arranged within the frame (102) to define a viewing window (50); and an electrically conductive mesh (90) spanning the viewing window (50). Further, the mesh (90) comprises a plurality of carbon nanotubes and is embedded in the substrate (10) to shield the microwave radiation generated in the oven (200) from reaching an exterior of the door frame (102).
