Oriented Assembly of Metamaterials

Kathleen J. Stebe,1,* Eric Lewandowski,1 Moniraj Ghosh2

Regular assemblies of colloidal particles have many potential uses from self-assembled electronics to biosensors. Recent advances in particle self-assembly suggest that such assemblies may also provide a simple route to metamaterials at infrared and visible length scales. Such metamaterials may, for example, be used to create cloaking devices or light-based circuits based on manipulations of local optical electric fields rather than on the flow of electrons (1).
