Zusammenfassung:	A method of forming a viewing panel for a microwave oven can comprise: placing a film including a conductive coating into a mold and molding a substrate to a surface of the film having the conductive coating to form the viewing panel; or injection molding a substrate and applying a conductive coating to a surface of the substrate after molding to form the viewing panel; wherein the substrate is selected from a transparent polymer or glass; the conductive coating has an EMI shielding effectiveness of greater than 25 d B from 30 MHz to 3.0 GHz as determined by ASTM D4935; and the viewing panel has a transmittance of greater than or equal to 50% of incident light having a frequency of 430 THz to 790 THz.
