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 ...

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 ...

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 ...

Periodic arrangements of chiral scatterers providing negative refractive index bi-isotropic media
(American Physical Society, 2008)
The main goal of this contribution is to show that periodic arrangements of chiral scatterers can be the basis for the development of three dimensional and isotropic negative refractive index artificial media. Three ...

Correct denition of the Poynting vector in electrically and magnetically polarizable medium reveals that negative refraction is impossible: comment
(Optical Society of America, 2009)
It is shown that, when all macroscopic currents associated with the electric and magnetic polarizability are properly accounted for, the standard expression for the Poynting vector and the average work exerted by the ...

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 ...

Towards a systematic design of isotropic bulk magnetic metamaterials using the cubic point groups of symmetry
(American Physical Society, 2007)
In this paper, a systematic approach to the design of bulk isotropic magnetic metamaterials is presented. The roles of the symmetries of both the constitutive element and the lattice are analyzed. For this purpose, it is ...

Analytical theory of extraordinary optical transmission through realistic metallic screens
(Optical Society of America, 2010)
An analytical theory of extraordinary optical transmission (EOT) through realistic metallic screens perforated by a periodic array of subwavelength holes is presented. The theory is based on our previous work on EOT ...

Analytical theory of extraordinary transmission through metallic diffraction screens perforated by small holes
(Optical Society of America, 2009)
In this letter, the problem of extraordinary (ET) transmission of electromagnetic waves through opaque screens perforated with subwave- length holes is addressed from an analytical point of view. Our purpose was to find a ...
