Near-perfect tunneling and amplification of evanescent electromagnetic waves in a waveguide filled by a metamaterial: Theory and experiments
(American Physical Society, 2005)
Amplification of evanescent electromagnetic waves by a metamaterial slab is still a controversial issue. Metallic waveguides operating in cutoff provide a unique physical environment to produce and study these waves because ...

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 ...

Three-dimensional superresolution in metamaterial slab lenses: Experiment and theory
(American Physical Society, 2005)
This paper presents a theoretical and experimental study on the viability of obtaining two- and three-dimensional superresolution (i.e., resolution overcoming the diffraction limit for all directions in space) by means of ...

Babinet principle applied to the design of metasurfaces and metamaterials
(American Physical Society, 2004-11-05)
The electromagnetic theory of diffraction and the Babinet principle are applied to the design of artificial metasurfaces and metamaterials. A new particle, the complementary split rings resonator, is proposed for the design ...

Artificial magnetic metamaterial design by using spiral resonators
(American Physical Society, 2004)
A metallic planar particle, that will be called spiral resonator (SR), is introduced as a useful artificial atom for artificial magnetic media design and fabrication. A simple theoretical model which provides the most ...

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 ...
