Analysis of radio wave propagation for ISM 2.4GHz wireless sensor networks in inhomogeneous vegetation environments
(2014)
Contribución a congreso / Biltzarrerako ekarpena,
The use of wireless networks has been extended in an exponential growing due to the improvement in terms of battery life and low consumption of the devices. However, it is highly important to conduct previous radio propagation ...
Fire in the woods or fire in the boiler: implementing rural district heating to reduce wildfire risks in the forest-urban interface
(ElsevierThe Institution of Chemical Engineers, 2015)
Artículo / Artikulua,
Many rural communities in British Columbia (western Canada) are at risk from wildfire. This risk will increase over time as a result of climate change because of higher average temperatures, longer growing seasons, and ...
Optical fiber refractometers based on sputtered indium tin oxide coatings
(IEEE, 2011)
Contribución a congreso / Biltzarrerako ekarpena,
This work presents the fabrication of optical fiber
refractometers based on indium tin oxide (ITO) coatings
deposited by sputtering with response in the visible spectral
region. ITO thin-films have been sputtered by ...
Hydrogen-based energy storage for a distributed generation system
(Spanish Hydrogen Association, 2016)
Contribución a congreso / Biltzarrerako ekarpena,
One of the most typical distributed generation systems are electrical microgrid, which consist on small electrical
grids, generally connected to the main grid, with a decentralized management structure. Electrical microgrids ...
Simplified Brillouin sensor for structural health monitoring applications based on passive optical filtering
(SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
We present a simplified configuration for distributed Brillouin optical time domain analysis sensors. The technique is based on passive optical filtering of the spectral components generated in an RF-pulse-modulated optical ...
Comparison of linear and and small-signal models for inverter-based microgrids
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Frequency and voltage regulation in droop-based microgrids is generally modeled using small-signal analysis. In order to ensure accuracy, existing models do not decouple real and reactive power responses. However, the ...
Experimental study of the antenna influence in RTLS based-on RFID
(IEEE, 2012)
Contribución a congreso / Biltzarrerako ekarpena,
Nowadays Real-time localization systems (RTLS)
are growing up very quickly but there are some remaining
issues which need to be analyzed. This paper presents an
experimental study that shows how different kind of antennas
can ...
Low profile THz periodic leaky-wave antenna
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, a 0.566THz flat leaky-wave antenna, consisting of a central λ0/2 slot surrounded by straight parallel wedge corrugations, is numerically and experimentally analyzed. Simulations show a moderately high gain ...
All-metallic ε-near-zero (ENZ) lens based on ultra-narrow hollow rectangular waveguides: experimental results
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Here we perform numerical and experimental investigation of plano-concave all-metallic ε-near-zero (ENZ) lens with operational frequency f = 144 GHz. The ENZ lens is achieved by stacking an array of narrow hollow rectangular ...
Parametric study of pin surface used to suppress undesired modes in a packaged W-band microstrip receiver
(IEEE, 2013)
Contribución a congreso / Biltzarrerako ekarpena,
A pin surface structure has been used in order to
suppress undesired modes in a packaged W-band RF front-end
receiver. A parametric analysis has been carried out in order to
determine the optimum dimensions. Resonances ...
