Compact pillbox reflector based on geodesic lens
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
We propose a pillbox antenna in combination with a geodesic lens at 60 GHz. The antenna is implemented in a dual-layer parallel plate waveguide. The waves from a geodesic lens in a first layer, after being reflected by a ...
Low-voltage CMOS bulk-driven buffer with bootstrapping technique for gain enhancement and THD-noise reduction
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a bootstrapping technique is applied to a bulk-driven voltage buffer for canceling the gate-source transconductance in order to improve the cell gain, the linearity and reduce the input-referred noise. The ...
Filtro paso banda en tecnología groove gap waveguide con altura de pines reducida para facilitar su fabricación
(Universidad de Málaga, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, a novel topology of groove gap
waveguide (GGW) technology is presented to facilitate the
fabrication process by Computer Numerical Control (CNC)
milling. GGW has been proposed as an interesting alternative ...
Modelling and operation of 6-pulse thyristor rectifiers for supplying high power electrolyzers
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
This paper presents a detailed analysis of a
6-pulse thyristor rectifier aimed at supplying high
power electrolyzers. For this purpose, an analytical model of
the three-phase controlled rectifier with AC-side
inductance ...
Design alternatives for a submm-wave Fabry-Perot cavity antenna
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
This paper discusses different design alternatives for a high gain planar antenna at 240 GHz. The antenna is based on a Fabry-Perot configuration, where two different partial reflection surfaces (PRS) are considered: a ...
Alfalfa quality detection by means of VIS-NIR optical fiber reflection spectroscopy
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
A first approach study for the classification of alfalfa (medicago sativa) quality has been performed by means of VIS-NIR optical fiber reflection spectroscopy. Reflection spectral data has been obtained from alfalfa samples ...
Compensation of phase-noise in pulse-compression phase-sensitive OTDR sensors
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
We introduce a technique to compensate the performance impairments due to the laser phase noise in long-range pulse-compression DAS sensors. Experiments demonstrate the use of the longest duration pulse compression waveform ...
Quasi-distributed vibration analysis of a cantilever beam using OFDR and weak reflectors
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
This work evaluates the performance of a quasi-distributed in-line velocimeter based on OFDR and weak reflectors to measure vibration every 10 cm, using a cantilever beam under free-end damping and during an impact-hammer test.
Long-range and high-resolution traffic monitoring based on pulse-compression DAS and advanced vehicle tracking algorithm
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate traffic monitoring over tens of kilometres of road using an enhanced distributed acoustic sensing system based on optical pulse compression and a novel transformed-domain-based processing scheme with enhanced ...
Bloch surface wave resonances generated with dielectric stack of high refractive index contrast deposited on a D-shaped optical fiber for sensing applications
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
A 5-layer stack composed of TiO2 and Al2O3, two materials with a high refractive index contrast, was deposited on a D-shaped fiber to generate Bloch surface wave resonances with an improved figure of merit.
