Using a collective coordinate numerical optimization procedure, we construct ground-state configurations of interacting particle systems in various space dimensions so that the scattering of radiation exactly matches a prescribed pattern for a set of wave vectors. We show that the constructed ground states are, counterintuitively, disordered i.e., possess no long-range order in the infinite-volume limit. We focus on three classes of configurations with unique radiation scattering characteristics: i “stealth” materials, which are transparent to incident radiation at certain wavelengths; ii “super-ideal” gases, which scatter radiation identically to that of an ensemble of ideal gas configurations for a selected set of wave vectors; and iii “equi-luminous” materials, which scatter radiation equally intensely for a selected set of wave vectors. We find that ground-state configurations have an increased tendency to contain clusters of particles as one increases the prescribed luminosity. Limitations and consequences of this procedure are detailed. © 2008 American Institute of Physics. DOI: 10.1063/1.2961314
