Straightforward extension of canonical microwave metamaterial structures to optical and IR frequency dimensions is complicated by both the size scale of the resulting structures, requiring cutting edge lithography to achieve the requisite line-widths, as well as limitations on assembly/construction into final geometry. We present a scalable fabrication approach capable of generating metamaterial structures such as split ring resonators and split wire pairs on a micron/sub-micron size scale on concave surfaces with a radius of curvature ~ SRR diameter. This talk outlines the fabrication method and modeling/theory based interpretation of the implications of curved metamaterial resonators.
