Image acceleration in parallel magnetic resonance imaging by means of metamaterial magnetoinductive lenses
(American Institute of Physics, 2012)
Parallel Magnetic Resonance imaging (pMRI) is an image acceleration technique which takes advantage of localized sensitivities of multiple receivers. In this letter, we show that metamaterial lenses based on capacitively-loaded ...

Metallo-dielectric core-shell nanospheres as building blocks for optical three-dimensional isotropic negative-index metamaterials
(Institute of Physics Publishing, 2011)
Materials showing electromagnetic properties that are not attainable in naturally occurring media, so-called metamaterials, have been lately, and still are, among the most active topics in optical and materials physics and ...
