title: Coherent backscattering by two-sphere clusters.
abstract: Rigorous numerical solutions of Maxwell's equations are used to show, for what is believed to be the first time, that simple scattering systems composed of two interacting wavelength-sized spheres exhibit a coherent backscattering effect analogous to that observed previously for optically thick discrete random media comprising large numbers of scatterers.
