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 ...

Efficient analysis of magnetostatic surface waves in printed and suspended ferrite loaded strip lines
(Institute of Electrical and Electronics Engineers, 2001)
This paper analyzes the guidance of magnetostatic surface waves (MSSW) by a metallic strip printed on a ferrimagnetic slab or on a dielectric/ferrimagnetic structure (suspended configuration) in the frame of the magnetostatic ...

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 ...

Analytical theory of wave propagation through stacked fishnet metamaterials
(Optical Society of America, 2009)
This work analyzes the electromagnetic wave propagation through periodically stacked fishnets from zero frequency to the first Wood's anomaly. It is shown that, apart from Fabry-Perot resonances, these structures support ...

Efficient evaluation of reaction integrals in the EFIE analysis of planar layered structures with uniaxial anisotropy
(Institute of Electrical and Electronics Engineers, 2002)
This paper presents an efficient implementation of the electric-field integral-equation (EFIE) method to deal with planar anisotropic layered printed structures. A convenient treatment of the kernel of the integral equation ...

A new model of the carbonator reactor in the Calcium Looping technology for post-combustion CO2 capture
(Elsevier, 2015)
The Ca-Looping (CaL) process is considered as a promising technology for CO2 post-combustion capture in power generation plants yielding a minor penalty on plant performance as compared with other capture technologies ...

The settling of fine cohesive powders
(IOP Publishing Ltd., 2001-05-01)
We investigate the settling of an initially fluidized bed of a fine cohesive powder. Experimental results on the sedimentation rate cannot be fitted by theoretical and empirical equations existing in the literature and ...
