Characterization of wireless channel impact on wireless sensor network performance in public transportation buses
(IEEE, 2015)
Artículo / Artikulua,
Wireless communications systems are growing rapidly during the last two decades and they are gaining a significant role for multiple communication tasks within public transportation buses. In this work, the impact of ...
Analytical design methodology for Litz-wired high-frequency power transformers
(IEEE, 2015)
Artículo / Artikulua,
In the last quarter of a century, high-frequency
(HF) transformer design has been one of the major concerns to power electronics designers in order to increase
converter power densities and efficiencies. Conventional
design ...
Methodology for sizing stand-alone hybrid systems: a case study of a traffic control system
(Elsevier, 2018)
Artículo / Artikulua,
This paper proposes a methodology for sizing stand-alone hybrid photovoltaic-wind power generation systems. This methodology makes it possible to optimise the overall performance of the stand-alone system components, based ...
Ultra-compact planoconcave zoned metallic lens based on the fishnet metamaterial
(AIP Publishing, 2013)
Artículo / Artikulua,
A 1.5λ0 -thick planoconcave zoned lens based on the fishnet metamaterial is demonstrated experimentally at millimeter wavelengths. The zoning technique applied allows a volume reduction of 60% compared to a full fishnet ...
Mechanical 144GHz beam steering with all-metallic epsilon-near-zero lens antenna
(AIP Publishing, 2014)
Artículo / Artikulua,
An all-metallic steerable beam antenna composed of an ε-near-zero (ENZ) metamaterial lens is experimentally demonstrated at 144 GHz (λ0 = 2.083 mm). The ENZ lens is realized by an array of narrow hollow rectangular waveguides ...
Chirping techniques to maximize the power-handling capability of harmonic waveguide low-pass filters
(IEEE, 2016)
Artículo / Artikulua,
A novel chirping technique is applied to the design
of very high-power waveguide harmonic low-pass filters. The
technique could be used, for instance, to avoid multipactor
testing in multicarrier systems such as the ...

Compensation of forecast error in large PV plants with battery storage: associated strategies
(2017)
info:eu-repo/semantics/conferenceObject,
As penetration rates of utility-scale photovoltaics (PV) increases, large PV plants will participate in the daily wholesale electricity market in the same way that wind farms. Then, PV plant owner can receive some kind of ...
Static and dynamic characterization of a supercapacitor
(2014)
info:eu-repo/semantics/conferenceObject,
Supercapacitors (SCs) have recently received a major boost as a result of the development of multiple applications, such as the electric vehicle and electric microgrids. Storage systems consisting of SCs combined with ...
