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 ...

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 ...
