Abstract
An article has a curved surface. Disposed upon the curved surface is a plurality of patterns. Each pattern is defined by a plurality of spaced apart features attached to or projected into the curved surface. The plurality of features each have at least one neighboring feature having a substantially different geometry, wherein an average spacing between adjacent features is about 1 nanometer and about 1 millimeter in at least a portion of the curved surface. The plurality of spaced apart features are represented by a periodic function.
