Description
Summary:The dielectric tensor of four level atomic medium coupled with dielectric function of silver silica nano-composites material to modify dispersion relation of surface plasmon polaritons (SPPs). The rapid damping of SPPs is used to localized atomic particles in two dimension inverse position space. Directions, phases and intensity of the control field play important roles in the localization of atoms in a unit wavelength domain. Ten, six, four and two localization peaks are investigated by SPPs damping in different quadrants. A single broad localized peak symmetric about origin are also investigated. The theoretical work of this article may be useful for quantum information in Plasmonster technology.
