Application of visual hyperacuity to imaging and antenna systems
(2017)
Tesis doctoral / Doktoretza tesia,
El Sistema Visual Humano es capaz de llevar a cabo múltiples tareas, tales como enfocar
objetos a diferentes distancias u obtener imágenes con un amplio rango dinámico. Sin embargo,
la función más impresionante está ...
Development of ultrathin metasurface and partially reflective surface antennas for space applications
(2017)
Tesis doctoral / Doktoretza tesia,
La industria espacial ha estado siempre muy interesada en la evolución de las antenas que
se integran en los satélites. Se buscan soluciones que además de ser ligeras y compactas,
tengan un coste reducido. De esta forma ...
Leaky wave antennas, plasmonics and metamaterials in the terahertz
(2017)
Tesis doctoral / Doktoretza tesia,
La demostración del fenómeno de EOT en el rango de las milimétricas y las microondas y la presentación de la antena BE de onda de fuga en [53], propició el desarrollo de diversas antenas BE corrugadas, cada una de ellas ...
Metamaterials and extraordinary transmission structures applied to microwave, millimeter and terahertz waves devices
(2017)
Tesis doctoral / Doktoretza tesia,
Los metamateriales aparecen en los primeros años del siglo XXI como materiales artificiales
que presentan un comportamiento electromagnético de alguna manera exótico. Al mismo
tiempo, se descubre un nuevo fenómeno ...
Synthesis and design of novel metamaterial radiation structures
(2017)
Tesis doctoral / Doktoretza tesia,
The present thesis deals with the design and practical implementation of novel netamaterial planar
antenna structures based on Complementary Split Ring Resonator (CSRR) particles.
As CSRR particles display a very attractive ...
Analysis, characterization and modeling of interference sources on wireless communication systems in complex indoor scenarios
(2017)
Tesis doctoral / Doktoretza tesia,
This research work presents a novel methodology of assessing
wireless interferences on Wireless Sensor Networks (WSN) by the aid
of an in-house developed 3D Ray Launching method, which is a novel
deterministic approach ...
Optical sensors based on lossy-mode resonances
(Elsevier Science, 2017)

3D-printed 96 GHz bull’s-eye antenna with off-axis beaming
(IEEE, 2017)
Artículo / Artikulua,
Reducing the profile, footprint and weight of antennas embarked on aircrafts, drones or satellites has been a long pursued objective. Here we tackle this issue by developing a millimeter-wave 96 GHz elliptical Bull’s-Eye ...
Enhancement of signal-to-noise ratio in Brillouin optical time domain analyzers by dual-probe detection
(SPIE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a simple technique to enhance the signal-to-noise ratio (SNR) in Brillouin optical time-domain analysis sensors by the addition of gain and loss processes. The technique is based on the shift of the pump ...
Metasurface-based ultrathin carpet cloaks for millimeter waves
(2017)
Artículo / Artikulua,
A metasurface carpet cloak for millimetre-wave range with polarization independent
performance is experimentally demonstrated. It is shown that the cloak is able to mimic the
ground plane by fully restoring the amplitude ...
