Nonlinear metamaterial absorbers enabled by photonic doping of epsilon-near-zero metastructures
(American Physical Society, 2020)
info:eu-repo/semantics/article,
We theoretically demonstrate an approach for designing absorbers with strongly intensity-dependent absorption. The proposed absorbers consist of a spacer layer between a top resistive sheet and an underlying metallic ...
Electric discharge detection and localization using a distributed optical fiber vibration sensor
(Elsevier, 2020)
info:eu-repo/semantics/article,
Partial discharges are a type of electric discharge that cause localized breakdowns in a small portion of an insulating material without forming a complete rupture. In high power electric machines as well as in transmission ...
Building decentralized fog computing-based smart parking systems: from deterministic propagation modeling to practical deployment
(IEEE, 2020)
info:eu-repo/semantics/article,
The traditional process of finding a vacant parking slot is often inefficient: it increases driving time, traffic congestion, fuel consumption and exhaust emissions. To address such problems, smart parking systems have ...
A combination of a vibrational electromagnetic energy harvester and a giant magnetoimpedance (GMI) sensor
(MDPI, 2020)
info:eu-repo/semantics/article,
An energy harvesting device combined with a giant magnetoimpedance (GMI) sensor is presented to analyze low frequency vibrating systems. An electromagnetic harvester based on magnetic levitation is proposed for the electric ...
Development of an aptamer based luminescent optical fiber sensor for the continuous monitoring of Hg2+ in aqueous media
(MDPI, 2020)
info:eu-repo/semantics/article,
A fluorescent optical fiber sensor for the detection of mercury (Hg2+) ions in aqueous solutions is presented in this work. The sensor was based on a fluorophore-labeled thymine (T)-rich oligodeoxyribonucleotide (ON) ...
Vertically coupled InP/InGaAsP microring lasers using a single epitaxial growth and singleside lithography
(IEEE, 2020)
info:eu-repo/semantics/article,
The experimental demonstration of vertical microring lasers requiring only one single epitaxial growth and two single-side lithographic steps is presented, in what is the simplest fabrication scheme for such devices published ...
From 2G to 5G spatial modeling of personal RF-EMF exposure within urban public trams
(IEEE, 2020)
info:eu-repo/semantics/article,
The upcoming design and implementation of the new generation of 5G cellular systems, jointly with the multiple wireless communication systems that nowadays coexist within vehicular environments, leads to Heterogeneous ...
Aggregator to electric vehicle LoRaWAN based communication analysis in vehicle-to-grid systems in smart cities
(IEEE, 2020)
info:eu-repo/semantics/article,
Recently, there has been growing attention to the power grid management due to the increasing concerns on global warming. With the advancement in electric vehicles (EV) industry and the evolution in batteries, EVs become ...
A 3D ray launching time-frequency channel modeling approach for UWB ranging applications
(IEEE, 2020)
info:eu-repo/semantics/article,
Ultrawideband (UWB) has the ability to achieve decimetre level of ranging accuracy, hence, its wider usage nowadays in the field of positioning. In spite of the attractiveness of UWB, its performance is strongly dependent ...
Improved adaptive impedance matching for RF front-end systems of wireless transceivers
(Nature Research, 2020)
info:eu-repo/semantics/article,
In this paper an automatic adaptive antenna impedance tuning algorithm is presented that is based on quantum inspired genetic optimization technique. The proposed automatic quantum genetic algorithm (AQGA) is used to find ...
