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 ...

Self-complementary metasurface for designing narrow band pass/stop filters
(Institute of Electrical and Electronics Engineers, 2013)
A self-complementary metasurface is studied in this paper. The metasurface is a 2-D periodical arrangement of unit cells formed by a metallic printed split ring resonator and its complementary counterpart. It is demonstrated ...

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 ...

Demonstration of negative refraction of microwaves
(American Association of Physics Teachers, 2011)
An experimental setup to demonstrate negative refraction is described. A simple method for designing and fabricating a metamaterial with negative refractive index at microwave frequencies is discussed. The metamaterial ...
