Abstract

Certain example embodiments of this invention relate to coated articles having a metamaterial-inclusive layer, coatings having a metamaterial-inclusive layer, and/or methods of making the same. Metamaterial-inclusive coatings may be used, for example, in low-emissivity applications, providing for more true color rendering, low angular color dependence, and/or high light-to-solar gain. The metamaterial material may be a noble metal or other material, and the layer may be made to self-assemble by virtue of surface tensions associated with the noble metal or other material, and the material selected for use as a matrix. An Ag-based metamaterial layer may be provided below a plurality (e.g., 2, 3, or more) continuous and uninterrupted layers comprising Ag in certain example embodiments. In certain example embodiments, barrier layers comprising TiZrOx may be provided between adjacent layers comprising Ag, as a lower-most layer in a low-E coating, and/or as an upper-most layer in a low-E coating.
