Conference report
Restricted access - publisher's policyThe use of semiconductors, metals and conductive oxides in the process of fabrication of actual nano devices is at the front edge of nowadays technology, exploiting the properties of light propagation and localization at ... -
Harmonic generation from gold nanolayers: bound and hot electron contributions
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2021)
Conference report
Restricted access - publisher's policyCurrently, nanostructures are routinely fabricated and integrated in different photonic devices for a variety of purposes and applications. For instance, in order to engineer properly nano-antennas or filters, it is important ... -
Network-based ionospheric gradient monitoring to support GBAS
(ION Publications (The Institute of navigation), 2019)
Conference report
Open AccessIonospheric anomalies, like large ionospheric gradients, might produce a difference between the ionospheric error experienced bythe Ground Based Augmentation System (GBAS) reference station and the aircraft on approach. ... -
Sound directivity by PT-symmetric acoustic dipoles
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2021)
Conference report
Open AccessThe new physics of open-dissipative, non-Hermitian systems have become a fruitful playground to uncover novel physical phenomena, even in exotic or counterintuitive ways, especially in optics and, more recently, also in ... -
The unit peak discharge as a tool for flood magnitude comparison and analysis
(European Geosciences Union (EGU), 2021)
Conference report
Open AccessTo analyze the river floods dynamics, it is common to fix the observations of the flow at a characteristic checkpoint of the basin, showing its evolution over time: the hydrograph. A less common way of studying this ... -
How do the surface energy fluxes change when a more realistic land cover is included in the WRF model? An evaluation using BLLAST data
(European Geosciences Union (EGU), 2021)
Conference report
Open AccessIdeally, numerical weather prediction (NWP) and climate models should include a proper representation of the land surface to correctly simulate the surface energy fluxes and, ultimately, provide successful forecasts of ... -
Using Shack-Hartmann wavefront sensors and Zernike coefficients for beam characterisation: numerical procedures
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2017)
Conference report
Open AccessWhen using Shack-Hartmann wavefront sensors (SH) and Zernike coefficients (Zs) in applications where the position of the measurement and the point of interest are far apart, as it is common practice in ophthalmic optics, ... -
A Kinematic campaign to evaluate EGNOS 1046 maritime service
(ION Publications (The Institute of navigation), 2019)
Conference report
Open AccessGlobal Navigation Satellite Systems (GNSSs) have improved the efficiency and accuracy of transportation means. In terms of safety, the European Geostationary Navigation Overlay System (EGNOS) is providing vertical and ... -
RTK Feasibility Analysis for GNSS Snapshot Positioning
(ION Publications (The Institute of navigation), 2020)

Ionospheric scintillation model limitations and impact in GNSS-R missions
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThe ionosphere impacts radio-wave propagation, notably up to a few GHz. The main applications impacted by the ionosphere are GNSS positioning and timing, Earth Observations (especially low frequency SAR missions e.g. ... -
Radio-frequency interference location, detection and classification using deep neural networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessGlobal Navigation Satellite System (GNSS) signals are used in Earth Observation for Radio Occultation and Reflectometry. The increasing effects of Radio-Frequency Interferences (RFI) on the performance of these receivers ... -
OpenFOAM computational fluid dynamics simulations of thermal wind generation in mountain/valley configurations
(2021)
Conference report
Open AccessThermal winds appear in mountainous areas and valleys due to temperature gradients caused by the buoyancy effects associated with the diurnal heating-cooling cycle of the lower atmosphere. These winds develop over complex ...
