COATING FOR CURVED SURFACES

The present disclosure relates to coatings for curved surfaces. The transparent structure may have a plurality of layers, such as an inner layer and an outer layer, which may be formed from glass. The transparent structure may include a larger curved surface with composite bending and high geometric strain, and may include one or more layers. In order to apply a physical vapor deposition coating having a uniform thickness on a curved surface, the cathode power can be modulated during deposition, a mask having an opening curved to match the curved surface can be used, the cathode shape can be changed, the cathodes can sputter the coating outwardly toward the curved surface, and the thickness of the coating can be adjusted. The magnetic field may modulate the flux generated by the cathodes and/or may adjust the pressure and/or flow of the gas. By modifying the physical vapor deposition coater in one or more of these ways, the coating may have a uniform thickness across the curved surface and thus a uniform colo
