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 ...
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 ...
Enhanced radiation properties of a rectangular waveguide by means of a left handed media
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the results of experimental investigations to improve the gain between two
antennas by means of a Left Handed Material (LHM) are presented. The basic idea is the use
of a LHM media acting as a resonator ...
Design of a multifrequency antenna array with the use of left-handed superstrates
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the radiation performances of different antenna configuration
based on Left-Handed superstrates are presented. First of all, the behaviour of a Left-
Handed (LH) unit cell is analysed, showing a resonant ...
Design of low-cost smart accelerometers
(Universitat Politècnica de Catalunya, 2005)
Contribución a congreso / Biltzarrerako ekarpena,
The goal of this project is to design a low-cost smart accelerometer, making use of a piezoelectric
element as basic sensing material, and adding a
mixed-mode conditioning circuit.
Genetic breeding of edible mushrooms: from the genome to the production of new varieties of Pleurotus ostreatus
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006)
info:eu-repo/semantics/conferenceObject,
The breeding of new varieties of industrially cultivated edible mushrooms must proceed in the framework
defined by the breeding objectives, the biological characteristics of the material and the legal and
cultural ...
Evolución y futuro del Derecho civil navarro
(Gobierno de Navarra. Departamento de Presidencia, Justicia e Interior, 2002)
Contribución a congreso / Biltzarrerako ekarpena,
Las observaciones que se van a ir desgranando a lo largo de esta ponencia son fruto del análisis y de la reflexión sobre lo qué ha sido, es y puede llegar a ser en el futuro nuestro Derecho privativo. El recordatorio de ...
