Ordered titanium dioxide nanotubes for lossy-mode resonance-based humidity sensing
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Ordered titanium dioxide nanotubes on indium tin oxide as a structure supporting lossy-mode resonance is reported. Capability for application of the structure for optical humidity sensing is shown as an application example.
Evolutionary algorithms applied to multi-layered radiative cooling metamaterials
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
A newly design method for designing multi-layered radiative cooling metamaterials based on genetic algorithms (GAs) is exposed. The developed GA has been tested in three cases, resulting in three different structures that ...
Toroidal inductor design in multilevel DC-DC electric vehicle battery charger including high-frequency effects
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Inductor filters, such as the ones implemented in
DC-DC buck-boost converters for electric vehicle chargers,
have a major impact on the converter weight, volume and cost.
Thus, their design is key in order to obtain an ...
Outdoor performance of a CdTe based PV generator during 5 years of operation
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Together with the huge growth of the traditional
crystalline silicon (Si-x) PV manufacturers, other thin-film
solar cells have also emerged such as cadmium telluride
(CdTe) manufacturers. They are characterized by the ...
Control strategy for a droop-controlled grid-connected DFIG wind turbine
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
The application of droop control techniques without inner current control loops to doubly-fed induction generator (DFIG) based wind turbines does not allow to provide a stable response at all operating points in terms of ...
Comparison of a slotted SIW antenna covered with metasurface vs. a traditional array
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
In this article we compare two solutions to improve the radiation pattern of a slotted Substrate Integrated Waveguide (SIW) antenna: use of an E-plane array and covering it with a metasurface (MTS). To this aim, we compare ...
Multipactor breakdown analysis of Ku-band meandered low-pass filter
(2022)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, a very compact rectangular waveguide low-pass filter with meandered topology based on commensurate lines for Ku-band satellite applications is analysed for high-power handling capabilities. The device consists ...
Improvement of corona breakdown threshold (peak power handling) in smooth-profiled microstrip filters
(2022)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the PPHCs of two filter design techniques, stepped-impedance (SI) and smooth-profile (SP), are presented for four design prototypes. Smooth-profiled filters feature smooth variations in the characteristic ...
Mode transition during deposition of nanoscale ITO coatings on tilted fiber Bragg gratings
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
The mode transition phenomenon is experimentally demonstrated in tilted fiber Bragg gratings (TFBG) through the deposition of an indium tin oxide (ITO) thin film employing a DC sputtering machine.
Stable L-band fiber laser sensor using a backscattering-based multimode fiber reflector
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
A new and highly stable L-band fiber laser for sensing is demonstrated. An emission line at 1575.47 nm, was achieved using a special reflector. Good strain sensitivity, optical signal to noise ratio and output power stability ...
