A 3-D indoor analysis of path loss modeling using kriging techniques
(IEEE, 2022)
Artículo / Artikulua,
This study proposes a novel measurement-based method to predict and model three-dimensional (3-D) path loss in indoor scenarios, which first regresses 28 GHz measurements via median path loss modeling and then includes ...
Compact antennas in ridge gap waveguide with circular polarization
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
In this paper, two compact antennas in Ridge Gap Waveguide (RGW) technology, working at 60 GHz, with a high-purity circular polarization (CP) within a broad bandwidth are manufactured and measured. The antennas are fed ...
Grid-forming control for high-power inverters
(2022)
info:eu-repo/semantics/doctoralThesis,
La crisis medioambiental actual está potenciando el aumento de la demanda de fuentes renovables y sistemas de almacenamiento. La conexión de estas unidades de generación, que se realiza a través de inversores de alta ...
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 ...
Compact bull's-eye antenna in ridge gap waveguide with circular polarization at 60 GHz
(IEEE, 2021)
info:eu-repo/semantics/conferenceObject,
In this work, a Bull's-Eye (BE) antenna with circular polarization (CP) based on ridge gap waveguide (RGW) technology, working in the millimeter-wave band (60 GHz) is numerically and experimentally demonstrated. The structure ...
Cobalt detection using fluorescent dye layers
(MDPI, 2022)
Artículo / Artikulua,
In this paper, we report the preliminary results regarding the use of fluorescent dye calcein (C30H26N2O13) as a sensor for the detection of cobalt levels in aqueous solutions. The sensor cell based on calcein is built by ...
C and L band fiber lasers enhanced by ultrafast laser inscribed artificial backscatter reflectors
(Optica, 2022)
Artículo / Artikulua,
This letter presents an experimental comparison between two linear-cavity erbiumdoped fiber lasers (EDFL) assisted by two different artificial backscatter fiber-based reflectors.
Both reflectors were inscribed by femtosecond ...
Ring cavity erbium-doped fiber for refractive index measurements
(MDPI, 2022)
Artículo / Artikulua,
In this study, an interrogation system based on an erbium-doped fiber ring cavity for refractive index measurements is presented and experimentally demonstrated. This cavity ring includes a 1 × 3 coupler wherein one of the ...
Solar ultraviolet irradiance characterization under all sky conditions in Burgos, Spain
(MDPI, 2022)
Artículo / Artikulua,
Solar Ultraviolet Radiation (UVR), which is identified as a major environmental health hazard, is responsible for a variety of photochemical reactions with direct effects on urban and aquatic ecosystems, human health, plant ...
