Abstract
An article includes a transparent non-conducting layer, wherein a thickness of the transparent non-conducting layer continuously decreases in a first direction; and a transparent conducting layer on the transparent non-conducting layer, wherein a thickness of the transparent conducting layer continuously decreases in a direction opposite to the first direction. A thickness of the article is substantially uniform. A sheet resistance, R, to a flow of electrical current through the transparent conducting layer, varies as a function of position in the transparent conducting layer. A ratio of a value of maximum sheet resistance, R, to a value of minimum sheet resistance, R, in the transparent conducting layer is at least 1.5.
