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 ...
Design of a planar meta-surface based on dipoles and wires for antenna applications
(2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the design of a planar meta-surface based
on dipoles and wires is presented. The unit cell is formed
by three independent layers, which contain two parallel
dipoles and one wire. The behaviour of these ...
Study of the human eye working principle: an impressive high angular resolution system with simple array detectors
(IEEE, 2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper the working principle of the human
eye is studied since uses very simple detectors, cones
and rods, to provide an impressive high angular
resolution without using any kind of scanning
technique. Usually ...
Optimized feedhorn designs for compact antenna test range at Limoges University
(IEEE, 2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, high technology optimized feedhorn
designs are presented. These feedhorns have been
designed to improve the quite zone size and behaviour
at the Compact Antenna Test Range (CATR) of the
Antenna Research ...
A general beam-forming network made with CORPS
(2006)
Contribución a congreso / Biltzarrerako ekarpena,
A new beam-forming network concept is
introduced. This network is based in the design principles of
CORPS. The new proposed structure presents an
improvement in design over the traditional beam-forming
network since, ...
Multichannel blind deconvolution of impulsive signals
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this communication, the problem of blind deconvolution of transient, impulsive signals in a multichannel environment
is addressed. This kind of signals arise naturally, or are used
as external excitation, in many ...
Glottal spectrum based inverse filtering
(ISCA, 2003)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a new inverse filtering technique for the time-domain estimation of the glottal excitation is presented. This approach uses the DAP modeling for the vocal tract characterization, and a spectral model for the ...
Analysis and synthesis of vibrato in lyric singers
(2002)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper two aspects of the vibrato signal characterisation are
presented. First, an analysis method, which breaks down the musical
signal into its different partials, and decomposes them into two
separate ...
Unified analysis of glottal source spectrum
(ISCA, 2003)
Contribución a congreso / Biltzarrerako ekarpena,
The spectral study of the glottal excitation has traditionally
been based on a single time-domain mathematical model of
the signal, and the spectral dependence on its time domain
parameters. Opposite to this approach, ...
Resultados experimentales de la mejora de potencia radiada por un dipolo mediante un superstrato left-handed
(2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a comparison between the measured
radiation performances of a single dipole and a dipole with
a left handed superstrate based on a finite periodic repetition
of a unit cell is presented. First of all the ...
