Plasmonic optical properties in pairs of coated nanorods in near-field are investigated by finite element method. The coated nanorod is composed of a radically anisotropic dielectric core and a metallic shell. Numerical simulations show that for a finite radial permittivity ??r, with the increase of the tangential permittivity ??t, the position of the near-field intensity peak shifts to long wavelength...
The Goos-Hachen (GH) shift at the surface of chiral negative refraction media is analyzed theoretically. GH shifts are observed for both components of the reflected field near the respective critical angles. It is found that the shifts for both components of the reflected field are always positive when angles of incidence are larger than the second critical angle.
