Optical resonances in one-dimensional chains of dipole centers

The problem on the interaction of optical radiation with a nanostructure representing a onedimensional (linear) chain of electrodynamically interacting dipole centers - atoms - has been considered. It has been shown that the number of optical resonances of the nanostructure and the detuning of the resonance frequencies from the eigenfrequency of the atom are only determined by the internal parameters of the nanostructure. The dependence of the number of resonances on the number of atoms in the nanostructure has been established. For nanostructures having a symmetry center, the number of resonances in atoms depends also on the orientation of the nanostructure axis with respect to the direction of external-wave propagation.
