Broadband Extraordinary Transmission in a single sub-wavelength aperture
(Optical Society of America, 2010)
Coordinate transformation is applied to design an all-dielectric device for Extraordinary Transmission (ET) in a single sub-wavelength slit. The proposed device has a broadband feature and can be applied from microwave to ...

Rheology of magnetofluidized fine powders
(2010)
Usually a bed of solid particles °uidized by a gas is inherently unstable. Gas bubbles are rapidly formed at the onset of °uidization, which hinders the e±ciency of gas-solid contact. In the case of magnetizable particles, ...

Fishnet Metamaterials - Rules for Refraction and Limits of Homogenization
(Optical Society of America, 2010)
The perfectly conducting stacked fishnet metamaterial is studied in this paper. The analysis is based on a combination of the mode matching method together with the generalized eigenvalue problem, and takes into account ...

Tilted response of fishnet metamaterials at near-infrared optical wavelengths
(American Physical Society, 2010)
We study experimentally the transmission properties of Au-TiO2 -Au fishnet metamaterials in the near-infrared spectral range and analyze the change in the transmission resonances at varying angles of incidence and different ...
