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 ...

Experimental verification of extraordinary transmission without surface plasmons
(American Institute of Physics, 2009)
This letter provides an experimental demonstration of extraordinary transmission in a closed waveguide system loaded with an electrically small diaphragm. This is a situation where the standard surface plasmon polariton ...

Application of a Capacitively-loaded Split-ring Metamaterial Lens in a 0.3 T Magnetic Resonance Imaging System
(Elsevier, 2023)
In this work, it is demonstrated that metamaterial lenses can help to increase the signal-to-noise ratio of magnetic resonance imaging coils in low-field magnetic resonance imaging systems. In low-field magnetic resonance ...

Signal-to-noise ratio evaluation in resonant ring metamaterial lenses for MRI applications
(IOP Publishing Ltd., 2011)
In this paper, we present a method for the evaluation of the signalto- noise ratio in magnetic resonance imaging (MRI) coils loaded with resonant ring metamaterial lenses, in the presence of a conducting phantom resembling ...
