Coherence effects in scattering systems of two interacting dipoles at resonance.
Coherence effects in the backward-scattering direction, such as enhanced backscattering (EBS) and the appearance of a negative polarization branch (NPB), are investigated for a simple scattering system composed of two dipolelike particles separated by a fixed distance. The influence on these effects of coupling resonances between the particles is analyzed. The appearance of these coherent phenomena (EBS and NPB) and their relationship as a function of the optical properties of the particles (polarizability) and particle separation are also studied.
