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 ...

Two-dimensional numerical analysis of electroconvection in a dielectric liquid subjected to strong unipolar injection
(American Institute of Physics, 2012)
Two-dimensional numerical simulations are carried out to examine the problem of transient electroconvection stability of dielectric liquids subjected to unipolar injection. The entire set of electrohydrodynamics equations ...

Transmission through stacked 2D periodic distributions of square conducting patches
(American Institute of Physics, 2012)
In this paper, we study the transmissivity of electromagnetic waves through stacked two-dimensional printed periodic arrays of square conducting patches. An analytical circuit-like model is used for the analysis. The model ...

Common-mode suppression in microstrip differential lines by means of complementary split ring resonators: Theory and applications
(Institute of Electrical and Electronics Engineers, 2012)
This paper is focused on the application of complementary split-ring resonators (CSRRs) to the suppression of the common (even) mode in microstrip differential transmission lines. By periodically and symmetrically etching ...

New absorbing boundary conditions and analytical model for multilayered mushroom-type metamaterials: Applications to wideband absorbers
(Institute of Electrical and Electronics Engineers, 2012)
An analytical model is presented for the analysis of multilayer wire media loaded with 2-D arrays of thin material terminations, characterized in general by a complex surface conductivity. This includes the cases of ...

Analytical wideband model for strip/slit gratings loaded with dielectric slabs
(Institute of Electrical and Electronics Engineers, 2012)
This paper presents a fully analytical model to determine the transmission and reflection properties of planar 1-D distributions of metal strips or slits made in thin metal screens. In contrast with other analytical or ...

Enhanced transmission with a graphene-dielectric microstructure at low-terahertz frequencies
(American Physical Society, 2012)
Here, we report on the transmissivity of electromagnetic waves through a stack of monolayer graphene sheets separated by dielectric slabs at low-terahertz frequencies. It is observed that the multilayer structure possesses ...

Numerical study of dc-biased ac-electrokinetic flow over symmetrical electrodes
(AIP Publishing, 2012)
This paper presents a numerical study of DC-biased AC-electrokinetic (DC-biased ACEK) flow over a pair of symmetrical electrodes. The flow mechanism is based on a transverse conductivity gradient created through incipient ...

Quasi-analytical modeling of transmission/reflection in strip/slit gratings loaded with dielectric slabs
(Institute of Electrical and Electronics Engineers, 2012)
This paper presents a quasi-analytical approach to study the classic topic of transmission/reflection of electromagnetic waves through 1-D periodic arrays of strips/slits in metal screens. The approach is based on standard ...
