Leaky-Wave antennas with arbitrary radiation based on bianisotropic Huygens’ metasurfaces
Abdo-Sanchez, Maria Elena
; Epstein, Ariel; Eleftheriades, George V. (2018-06-05)
In this contribution, we present the application of Huygens’ metasurfaces (HMS) to the arbitrary design of leaky-wave antennas (LWAs). These metasurfaces have demonstrated their capabiity to tailor the electromagnetic waves ... -
Limitaciones del equilibrio de carga para la mejora de la calidad de experiencia en redes LTE
Marí-Altozano, María Luisa; Luna-Ramírez, Salvador; Toril-Genoves, Matias (URSI 2017, 2017)
Due to the huge increase in traffic and services in mobile networks, network management has changed its main focus from Quality of Service (QoS) to Quality of Experience (QoE). In addition, SON (Self Organizing Networks) ... -
Load balance performance analysis with a quality of experience perspective in LTE networks
Due to the huge increase in traffic and services in mobile networks, network management has changed its main focus from Quality of Service (QoS) to a Quality of Experience (QoE) perspective. In addition, Self Organising ... -
Logistic regression for BLER prediction in 5G
Ruiz Sicilia, Juan Carlos; Aguayo-Torres, Maria del Carmen (2020-10-09)
In this work, a block error rate (BLER) predictor for 5G based on logistic regression is presented. The regression is fed with transmission parameters and channel statistics. With these features, the predictor can model ... -
Long-term calibration analysis of scientific echosounders used in research vessels
Cordoba Selles, Pilar; Iglesias Marroig, Magdalena; Ventero Martín, Ana; Nava-Baro, Enrique (2019-07-31)
The use of scientific multifrequency echosounders like SIMRAD EK60 in resource-assessment surveys of small pelagic fish like sardine or anchovy, has been employed by the Spanish Institute of Oceanography (IEO) for more ... -
Loudspeaker Crossover Design (from analog to digital)
(2016-04-01)Loudspeaker systems are quite complex devices and considered ‘musical instruments’ for many HiFi-enthusiasts. However, from the technical point of view the description of an optimal loudspeaker seems to be simple: the ... -
Low limit of detection silicon photonic sensor with extremely-low-cost laser source
Leuermann, Jonas; Fernández-Gavela, Adrián; Lechuga, Laura M.; Sánchez-Postigo, Alejandro; Halir, Robert; Molina-Fernandez, Iñigo[et al.] (2020-10-06)
Integrated photonic biosensors have demonstrated low bulk detection limits down to 1e−7 refractive index units. Nevertheless, most rely on expensive optical sources, such as DFB lasers. Here, we experimentally demonstrate ... -
Low-cost step aerobics system with virtual aerobics trainer
Rosa, Alejandro; Barbancho-Perez, Isabel; Tardon-Garcia, Lorenzo Jose; Barbancho-Perez, Ana Maria (2014-06-30)
In this paper a low-cost step-aerobics instructor simulation system is presented. The proposed system analyses a given song to iden- tify its rhythmic pattern. Subsequently, this rhythmic pattern is used in order to ... -
Low-loss curved waveguide grating wavelength demultiplexer
Hadij ElHouati, Abdel; Ortega-Moñux, Alejandro; Wanguemert-Perez, Juan Gonzalo; Halir, Robert; Wang, Shurui; Schmid, Jens H.; Cheben, Pavel; Molina-Fernandez, Iñigo[et al.] (2021)
We demonstrate a compact wavelength demultiplexer for the silicon on insulator platform based on the curved waveguide grating (CWG) architecture. We mitigate off-chip radiation loss by enforcing the single beam condition ... -
