Pseudo-three-stage Miller op-amp with enhanced small-signal and large-signal performance
(IEEE, 2019)
Artículo / Artikulua,
A simple technique to implement highly power efficient class AB-AB Miller op-amps is presented in this paper. It uses a composite input stage with resistive local common mode feedback that provides class AB operation to ...
Subsampling OFDM-based ultrasonic data communication through metallic channels for monitoring of cargo containers
(IEEE, 2019)
Artículo / Artikulua,
An enhanced ultrasonic communication system based on piezoelectric transducers for monitoring of goods in cargo containers is presented. The proposed system consists of several sensors placed inside the container, whose ...
Controlling the direction of propagation of surface plasmons via graded index effective dielectric media
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work, we propose a mechanism to steer and tailor surface plasmon propagation by using graded index concepts. In this approach, a block of dielectric with fixed thickness is placed on top of a semi-infinite metal. ...
Overcoming the diffraction limit with high-index dielectric particles
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
In this communication, we propose and demonstrate the ability to produce photonic nanojets using high refractive index dielectric particles immersed in air. An extremely narrow focus is produced just at the output surface ...
Spatial characterization of personal RF-EMF exposure in public transportation buses
(IEEE, 2019)
Artículo / Artikulua,
New services and applications within vehicular environments employ multiple wireless communication systems,
within a Heterogeneous Network framework. In this context, evaluation of electromagnetic field impact is compulsory, ...
Energía sostenible: sin malos humos
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2019)
info:eu-repo/semantics/book,
¿Puede España ser sostenible energéticamente? Si alguna vez te has
planteado esta pregunta, o quieres saber en qué gastamos la energía y de
dónde podría ser obtenida, aquí encontrarás respuestas. Nuestros recursos ...
A GIS-based methodology for assigning experimental measurements of angular distribution of sky radiance and luminance to selected sky sectors
(Elsevier, 2019)
Artículo / Artikulua,
Mathematical models for the estimation of the angular distribution of diffuse radiance/luminance in the
sky describe the anisotropic character of diffuse solar radiation and daylight in the sky vault. In most of
these ...
Aluminum doped zinc oxide (AZO) coated optical fiber LMR refractometers. An experimental demonstration
(Elsevier, 2019)
info:eu-repo/semantics/article,
This work presents the experimental demonstration of lossy mode resonance generation by means of aluminum doped zinc oxide thin-films. The use of such material may allow to optimize the performance of LMR-based sensors, ...
Micro-drilled optical fiber for enhanced laser strain sensors
(SPIE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work, we present an experimental measurement of temperature and strain sensitivities of a micro-drilled optical
fiber (MDOF). The MDOF consisted of a quasi-randomly distributed reflector along a single mode fiber ...
Multiplexing optical fiber Fabry-Perot interferometers based on air-microcavities
(SPIE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work we demonstrate the multiplexing capability of new optical fiber Fabry-Perot interferometers based on airmicrocavities using a commercial FBG interrogator. Three optimized air-microcavity interferometer sensors ...
