Dimensional Resonances in Biatomic Nanostructures and the Characteristics of Their Holograms

Abstract

A self-consistent problem of determining the field at the location of atoms in a nanostructural object and also at different observation points beyond a group of atoms (a small object) in the wave and near zones is solved on the basis of a system of compatible equations for the light-wave electric field strength and optical equations for linear dipole oscillators. We proved the existence of two dimensional resonances in the nanostructural object that consists of two identical atoms, with each having a single isolated resonance. We show that the properties of dimensional resonances depend strongly on small displacements of atoms with respect to one another. Formulas are obtained for effective polarizabilities of atoms in the small object. Optical plane holograms of the small object were obtained by interference of the coherent field of the dipoles of the small object and of the reference coherent wave in a certain plane of observation points far from the small object in the wave zone at frequencies corresponding to dimensional resonances.
