Abstract
Assemblies containing a substrate with pockets for electromagnetically responsive particles can be made for a variety of uses, including, for example, display media, lenses, and color-changing fabric. The arrangement of these pockets can be selected to provide higher particle density than previously realized. The assembly includes an assembly substrate, particles, and a top coat layer.
