Design of a deployable helix antenna at L-Band for a 1-Unit CubeSat: from theoretical analysis to flight model results
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-05-01)
Article
Open AccessThe 3Cat-4 mission aims at demonstrating the capabilities of a CubeSat to perform Earth Observation (EO) by integrating a combined GNSS-R and Microwave Radiometer payload into a 1-Unit CubeSat. One of the greatest challenges ... -
In-cabin 120 GHz radar system for functional human breathing monitoring in a 3D scenario
(Íñigo Cuiñas Gómez, 2021)
Conference report
Open AccessDriving is one of the activities that takes a significant part of a person’s time, that is why monitoring vital signs is useful for the wellness of the occupants of the vehicle. One of the vital signs that provides more ... -
Vector spherical harmonic analysis and experimental validation of spherical shells illuminated with broadband, millimeter wave Gaussian beams: applications to corneal sensing
(2022-06-03)
Article
Open AccessCoupling to longitudinal modes of thin spherical shells, under Gaussian-beam illumination, was explored with a theoretical method based on Fourier-optics analysis and vector spherical harmonics and was scrutinized with an ... -
A parallel Monte Carlo method for solving electromagnetic scattering in clusters of dielectric objects
(Elsevier, 2022-08-15)
Article
Restricted access - publisher's policyIn this work, we develop a novel Monte Carlo method for solving the electromagnetic scattering problem for clusters of photonic particles. The method is based on a formal solution of the scattering problem as a modified ... -
Volcanic eruption of Cumbre Vieja, La Palma, Spain: A first insight to the particulate matter injected in the troposphere
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-05-20)
Article
Open AccessThe volcanic eruption of Cumbre Vieja (La Palma Island, Spain), started on 19 September 2021 and was declared terminated on 25 December 2021. A complete set of aerosol measurements were deployed around the volcano within ... -
On the locality of attention in direct speech translation
(Association for Computational Linguistics, 2022)
Conference lecture
Open AccessTransformers have achieved state-of-the-art results across multiple NLP tasks. However, the self-attention mechanism complexity scales quadratically with the sequence length, creating an obstacle for tasks involving long ... -
Compression of multibeam echosounders bathymetry and water column data
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-04-25)
Article
Open AccessOver the past decade, Multibeam Echosounders (MBES) have become one of the most used techniques in sea exploration. Modern MBES are capable of acquiring both bathymetric information on the seafloor and the reflectivity of ... -
A preliminary study on ionospheric scintillation anomalies detected using GNSS-R data from NASA CYGNSS mission as possible earthquake precursors
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-05-26)
Article
Open AccessIonospheric perturbations affect the propagation of electromagnetic waves. These perturbations, besides being a problem for space communications, satellite navigation, and Earth observation techniques, could also be used ... -
Calibration alignment sensitivity in corneal terahertz imaging
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-04-22)
Article
Open AccessImproving the longitudinal modes coupling in layered spherical structure contributes significantly to corneal terahertz sensing, which plays a crucial role in the early diagnosis of cornea dystrophies. Using a steel sphere ... -
Distributed nonlinear model and fast analysis for in-band IMD3 prediction of surface acoustic wave resonators
(Institute of Electrical and Electronics Engineers (IEEE), 2022-01-01)
Article
Open AccessThe motivation of this work is to analyze the in-band intermodulation distortion (IMD) occurring in surface acoustic wave (SAW) devices, using a recently developed fast method based on the input–output equivalent sources ... -
Method to measure reflection coefficient under CW high-power signals in SAW resonators
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Restricted access - publisher's policyImproving power handling and lifetime are key assets to ensure device performance and reliability. SAW resonators composed by very thin cross-section inter-digital transducer (IDT) structures make difficult to control the ... -
Out of band improved performance into a measured 5G N77 band transversal filter
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Restricted access - publisher's policyTransversal networks for electroacoustic filters had been proposed and manufactured recently. One of the main problems that arose in the first prototype were the spurious modes due to the mirror stack of the Solidly Mounted ...
