High-isolation leaky-wave array antenna based on CRLH-metamaterial implemented on SIW with ±30° frequency beam-scanning capability at millimetre-waves
(MDPI, 2019)
info:eu-repo/semantics/article,
The paper presents a feasibility study on the design of a new metamaterial leaky-wave antenna (MTM-LWA) used in the construction of a 1 × 2 array which is implemented using substrate-integrated waveguide (SIW) technology ...
Substrate-integrated photonic doping for near-zero-index devices
(Nature Research, 2019)
info:eu-repo/semantics/article,
Near-zero-index (NZI) media, a medium with near zero permittivity and/or permeability, exhibits unique wave phenomena and exciting potential for multiple applications. However, previous proof-of-concept realizations of NZI ...
Self-referenced optical fiber sensor for hydrogen peroxide detection based on LSPR of metallic nanoparticles in layer-by-layer films
(MDPI, 2019)
info:eu-repo/semantics/article,
Intensity-based optical fiber sensors are one of the most studied sensor approaches thanks to their simplicity and low cost. Nevertheless, their main issue is their lack of robustness since any light source fluctuation, ...
Implementation of radiating elements for radiofrequency front-ends by screen-printing techniques for Internet of Things applications
(MDPI, 2019)
info:eu-repo/semantics/article,
The advent of the Internet of Things (IoT) has led to embedding wireless transceivers into a wide range of devices, in order to implement context-aware scenarios, in which a massive amount of transceivers is foreseen. In ...
Real time measuring system of multiple chemical parameters using microstructured optical fibers based sensors
(IEEE, 2018)
info:eu-repo/semantics/article,
In this paper, a multiplexing system for simultaneous interrogation of optical fiber sensors which measure different parameters is presented and validated. The whole system has been tested with 6 different sensing heads ...
Watt-level green random laser at 532 nm by SHG of Yb-doped fiber laser
(Optical Society of America, 2018)
info:eu-repo/semantics/article,
We have developed a Watt-level random laser at 532 nm. The laser is based on a 1064 nm random distributed ytterbium-gain assisted fiber laser seed with a 0.35 nm line-width and 900 mW polarized output power. A study for ...
Mapping the conductivity of graphene with electrical resistance tomography
(Nature Research, 2019)

Electronic applications of large-area graphene films require rapid and accurate methods to map their electrical properties. Here we present the first electrical resistance tomography (ERT) measurements on large-area graphene ...
Lossy mode resonance sensors based on lateral light incidence in nanocoated planar waveguides
(Nature Research, 2019)
info:eu-repo/semantics/article,
The deposition of an indium oxide (In2O3) thin film on conventional planar waveguides (a coverslip and a glass slide) allows generating lossy mode resonances (LMR) by lateral incidence of light on the waveguide and by ...
Fiber-based early diagnosis of venous thromboembolic disease by label-free D-dimer detection
(Elsevier, 2019)
info:eu-repo/semantics/article,
D-dimer is a useful diagnostic biomarker for deep vein thrombosis or pulmonary embolism, collectively referred to as venous thromboembolism (VTE). The ability to detect in real-time the amount of D-dimer with a fast and ...
Distributed dynamic strain sensing via perfect periodic coherent codes and a polarization diversity receiver
(IEEE, 2019)
info:eu-repo/semantics/article,
Rayleigh scattering-based dynamic strain sensing with high spatial resolution, fast update rate, and high sensitivity is highly desired for applications such as structural health monitoring and shape sensing. A key issue ...
