Electromagnetic cloaking with canonical spiral inclusions
(IOP Publishing Ltd., 2008)
Artículo / Artikulua,
We report an electromagnetic cloaking structure that is composed of identical canonical spiral particles. By using the Clausius-Mosotti formula, the electric and magnetic polarizabilities of a single spiral particle are ...
Dipolos y metamateriales: mejora de las características de radiación
(2004)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, pass band properties of Left Handed Media (LHM) are demonstrated. These properties have been used in order to make a LHM super-substrate that is put over a dipole antenna. This super-substrate is going to ...

In this work, pass band properties of Left Handed Media (LHM) are demonstrated. These properties have been used in order to make a LHM super-substrate that is put over a dipole antenna. This super-substrate is going to ...
High efficient dipole antennas by using left-handed superstrates
(2004)
Contribución a congreso / Biltzarrerako ekarpena,
This paper deals with pass band properties of Left Handed Media (LHM) to enhance dipole antenna performances. The LHM properties have been used in order to make high directivity antennas with good return loss features. The ...
A metamaterial T-junction power divider
(IEEE, 2007)
Artículo / Artikulua,
A metamaterial based compact microstrip T-junction
power divider working at 10 GHz is proposed. The metamaterial
unit cell consists of microstrip gaps and via holes whose behavior
is equivalent to the combination of ...

(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.
Análisis de efecto de un superestrato left-handed en la apertura de una guía rectangular
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, results showing the experimental verification of the gain improvement of a rectangular waveguide antenna when a left-handed material (LHM) is used as superstrate are presented. The improvement has been ...
Radiation performances of a multifrequency dipole antenna array with a left handed superstrate
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the radiation performances of a multifrequency antenna array (MFAA) which consists of
two dipoles (1 and 3) that are radiating at 9.57 GHz and other one (dipole 2) radiating at 11.98 GHz are
presented. In ...
Radiation performances of a dipole array configuration inserted in a left-handed media
(IEEE, 2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the radiation improvements achieved when Left Handed Media (LHM) are combined with dipole antennas has been analysed. The behavior of two dipole antennas in array configuration when a Left Handed superstrate ...
