Abstract :
In this presentation, we study the possibilities of enhancing losses in plasmonic-dielectric layered structures and tailoring their frequency dependence towards elimination of the dispersion variation. This is done by building the material inclusions as radially anisotropic (RA) spheres which are externally isotropic.
