Claim:
1. A multi-layer device comprising a first substrate and a layered stack that is transmissive to electromagnetic radiation having a wavelength in the range of infrared to ultraviolet on a surface of the first substrate, the layered stack comprising a first electrically conductive layer and a first current modulating structure each covering at least 0.01 m 2 of the surface of the first substrate, the first electrically conductive layer being between the surface of the first substrate and the current modulating structure, the current modulating structure comprising a patterned layer, wherein the first electrically conductive layer has a spatially varying sheet resistance, R s , that varies as a function of position in the first electrically conductive layer, a contour map of the sheet resistance, R s , as a function of position within the first electrically conductive layer contains a set of isoresistance lines and a set of resistance gradient lines normal to the isoresistance lines, and the sheet resistance along a gradient line in the set generally increases, generally decreases, generally increases until it reaches a maximum and then generally decreases, or generally decreases until it reaches a minimum and then generally increases.
