Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for producing meander-line polarizers. In some implementations, a meander-line polarizer includes a dielectric substrate made of a polyester polymer material and meander-line arrays formed on a surface of the dielectric substrate. Each meander-line array includes a sequence of alternating perpendicular conductive traces that are formed the surface of the dielectric substrate by applying conductive ink to the surface of the dielectric substrate using a template that defines a location and dimensions of each conductive trace of each meander-line array.
