Patent ID: 8181338

Claim:
A method of providing a multilayer composite of layers of a dielectric film and an electrically conductive layer, the method comprising: forming a shape defining element through roll-to-roll embossing using an embossing drum having a corrugated microstructure about its circumference to providing the shape defining element with a surface pattern of raised and depressed surface portions corresponding to the corrugated microstructure of the embossing drum, the surface pattern having a periodically repeated sub-pattern several wavelengths long corresponding to the circumference of the embossing drum, providing a liquid polymer composition onto the surface pattern to form a first film of dielectric material having a front surface with a replicated surface pattern of raised and depressed surface portions and an opposite rear surface, the replicated surface pattern of raised and depressed surface portions including a periodically repeated sub-pattern several wavelengths long corresponding to the circumference of the embossing drum, depositing an electrically conductive layer onto the replicated surface pattern to form a first composite, providing a second composite comprising a film with a front surface and an opposite rear surface, the front surface comprising a surface pattern of raised and depressed surface portions, depositing an electrically conductive layer covering at least a portion of the surface pattern, arranging the first composite on the second composite, and fixating the position of the first composite relative to the second composite.
