Arrangements of via-holes in microstrip lines as metallodielectric periodic structures
(Wiley, 2000)
Artículo / Artikulua,
In this paper, the use of via holes in microstrip lines to design periodic structures that can be regarded as metallodielectric electromagnetic crystals is analyzed. The proposed novel periodic structures achieve a notably ...
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 ...

Modern corrugated horn antenna design for extremely low sidelobe level
(2003)
Contribución a congreso / Biltzarrerako ekarpena,
The present paper deals with the design of modern corrugated horn antennas for extremely low sidelobe level with the
use of the well known corrugated Gaussian Profiled Horn Antenna aperture (corrugated GPHA’s) to improve ...
Choked-gaussian corrugated horn antenna design small global coverage horn antenna for TT&C with extremely low sidelobe level
(2003)
Contribución a congreso / Biltzarrerako ekarpena,
Extremely low sidelobe horn antennas are often required for the actual technology. This type of horn antennas are
important to avoid interference with other systems.
In this paper we describe a new design implementing a ...
Diseño de una antena dual gaussiana de doble profundidad de corrugación
(2003)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a new design of a dual-band corrugated horn antenna is presented. The design is based on a gaussian profile to allow high pattern symmetry, low-crosspolar levels and low-side-lobes over a wide frequency range. ...
Estado del arte de las antenas que combinan corrugaciones horizontales y verticales
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In the present paper the state of the art, possibilities, advantages and disadvantages of the patented corrugated horn antennas that combine horizontal and vertical corrugations is being covered. These rather new type and ...
Desfasadores para microstrip empleando metamateriales
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper an application of LH materials at
microwave frequencies (10GHz) is presented. A compact
quarter-wave impedance transformer is proposed using
alternating sections of left handed media (LHM) and
conventional ...
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 ...
