Design of beam-forming networks for scannable multi-beam antenna arrays using CORPS
(EMW Publishing, 2008)
Artículo / Artikulua,
This paper deals with the design of beam-forming
networks (BFN) for scannable multibeam antenna arrays using
Coherently Radiating Periodic Structures (CORPS). This design of
CORPS-BFN considers the optimization of the ...
Negative refraction through an extraordinary transmission left-handed metamaterial slab
(American Physical Society, 2009)
Artículo / Artikulua,
In this work we present numerical and experimental results of negative refraction through a negative index
metamaterial based on miniaturized extraordinary transmission stacked subwavelength hole arrays, also known
as ...
Polarization selection with stacked hole array metamaterial
(AIP Publishing, 2008)
Artículo / Artikulua,
Polarization rotation or selection appears in materials with optical activity, or those with Faraday
effect, or in liquid crystals. In this letter we present a structure, with an analogous response, using
stacked ...
Converging biconcave metallic lens by double-negative extraordinary transmission metamaterial
(AIP Publishing, 2009)
Artículo / Artikulua,
In this letter we present simulation and experimental results of a left-handed converging biconcave
metallic lens made of stacked subwavelength hole arrays SSHAs working in the millimeter wave
range with additional ...
Experimental demonstration of phase resonances in metallic compound gratings with subwavelength slits in the millimeter wave regime
(AIP Publishing, 2009)
Artículo / Artikulua,
We provide experimental evidence of phase resonances in metallic periodic structures in which each
period comprises several subwavelength slits of the same width. We have analyzed and measured
the response of these ...
Utilizando CORPS-BFN para alimentar sistemas de antenas de múltiples haces
(2007)
Contribución a congreso / Biltzarrerako ekarpena,
This paper present an application of the Coherently
Radiating Periodic Structures - CORPS on the design of a Beam
Forming Network -BFN. The Named CORPS-BFN is a novel

Low profile multi-frequency dipole antenna array based on planar meta-surfaces
(IEEE, 2007)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the radiation performance of a low profile multi-frequency dipole antenna array with a
planar meta-surface is presented. The meta-surface consists of two closely located parallel grids of short
dipoles and ...
EBG superstrate antenna for WAAS bands
(2008)
Contribución a congreso / Biltzarrerako ekarpena,
Multiband antennas can simplify considerably the complexity of receivers and transmitters,
reducing the size and the mass of the conventional configurations. On the other hand, applications with
high directivity requirements ...
Planar DNG superstrate for dipole antenna gain enhancement
(2007)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a volumetric double-negative (DNG) superstrate based on grids of dipoles and wires for dipole
antenna applications is proposed.
Mejoras de los parametros de radiacion de una antena choque-gaussiana para cobertura global
(2004)
Contribución a congreso / Biltzarrerako ekarpena,
Extremely low sidelobe horn antennas are often required for the actual technology. This type of horn antennas is important to avoid interference with other systems.
In this paper a novel design, consisting in attaching ...
