In this work, the behavior of a Complementary Split Ring Resonator (CSRR) operating within the
quasi-static resonance regime and embedded in a composite stratified Substrate Integrated
Waveguide (SIW) with two different ...
Brillouin optical time-domain analyzer for extended sensing range using probe dithering and cyclic coding
(SPIE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
We present an enhanced performance Brillouin optical time-domain analysis sensor that uses dual probes waves with optical frequency modulation and cyclic coding. The frequency modulation serves to increase the probe power ...
On the stability criteria for inverter current control loops with LCL output filters and varying grid impedance
(IEEE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
The use of LC and LCL filters and grid impedance variations are creating new challenges on the controller design for current control loops of photovoltaic and wind turbine inverters. In the design process, stability criteria ...

Enhancement of the dynamic range in slope-assisted coherent brillouin optical time-domain analysis sensors
(IEEE, 2017)
Artículo / Artikulua,
We present two techniques that provide an extension of the dynamic range of coherent Brillouin optical time-domain analysis (BOTDA) sensors for dynamic measurements. This type of BOTDA sensors rely on self-heterodyne ...
Gaze estimation: a mathematical challenge
(2017)
info:eu-repo/semantics/doctoralThesis,
El interés en los sistemas de eye tracking está creciendo significativamente en la actualidad. Aunque la tecnología de eye tracking puede parecer nueva, el estudio del movimiento del ojo ya empezó a principios del siglo ...

In this work, a preliminary study of the behavior of two different interferometric fiber optic sensors and two different wavelength selective fiber optic sensors is performed. A photonic cristal fiber Fabry-Pérot interferometer, ...
Polyaniline deposition on tilted fiber Bragg grating for pH sensing
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
In this paper, we present the results of a new pH sensor based on a polyaniline (PAni) coating on the surface of a tilted fiber Bragg grating. The pH-sensitive PAni was deposited by in situ chemical oxidative polymerization. ...
Simultaneous temperature and vibration monitoring using an all-PM fiber loop mirror interferometer
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
In this work, an all-polarization maintaining fiber loop mirror interferometer is presented and validated as vibration and temperature sensor without crosstalk between measurands. The system is entirely built using ...
