Silver nanorod has a very good plasmonic response to optical waves, that is, it exhibits some extraordinary near-field optical properties. In this paper, we investigate the plasmonic reaction of nanorods to polarized visible light. Not only a single nanorod is studied, but also two nanorods and an array of nanorods are manifested. The reemitted pattern of the nanorods array declares that a subwavelength...
In this paper we discuss eigenmodes propagating in plasmonic coaxial waveguides of nano-scale dimensions. Plasmonic nano-cables with an elliptic shape of a central rod are proposed. Break of the azimuthal symmetry makes it easier to excite dipole-type modes. We show that waveguides with central rods, having shapes of crossed ellipses, can be used for transfer of optical signals with orthogonal polarizations...
