Field enhancement at metallic interfaces due to quantum confinement
Z. Fatih Öztürk, Sanshui Xiao, Min Yan +3
We point out an apparently overlooked consequence of the boundary conditions obeyed by the electric displacement vector at air-metal interfaces: the continuity of the normal compon…
Coupled-resonator optical waveguides: Q-factor and disorder influence
J. Grgic, E. Campaioli, S. Raza +2
Coupled resonator optical waveguides (CROW) can significantly reduce light propagation pulse velocity due to pronounced dispersion properties. A number of interesting applications…
Achieving Anisotropy in Metamaterials made of Dielectric Cylindrical Rods
Liang Peng, Lixin Ran, Niels Asger Mortensen
We show that anisotropic negative effective dispersion relation can be achieved in pure dielectric rod-type metamaterials by turning from the symmetry of a square lattice to that o…
Nearly-zero transmission through periodically modulated ultrathin metal films
Sanshui Xiao, Jingjing Zhang, Liang Peng +4
Transmission of light through an optically ultrathin metal film with a thickness comparable to its skin depth is significant. We demonstrate experimentally nearly-zero transmission…
Cloaking of levitating objects above a ground plane
Jingjing Zhang, Yu Luo, Niels Asger Mortensen
An approach to hiding objects levitating or flying above a conducting sheet is suggested in this letter. The proposed device makes use of isotropic negative-refractive-index materi…
Influence of confining potentials on the exchange coupling in double quantum dots
Jesper G. Pedersen, Christian Flindt, Antti-Pekka Jauho +1
We report simple expressions for the exchange coupling in double quantum dots calculated within the Heitler-London and the Hund-Mulliken approximations using four different confini…
Minimizing the scattering of a non-magnetic cloak
Jingjing Zhang, Yu Luo, Niels Asger Mortensen
Nonmagnetic cloak offers a feasible way to achieve invisibility at optical frequencies using materials with only electric responses. In this letter, we suggest an approximation of…
