Tunable beam steering enabled by graphene metamaterials
(Optical Society of America, 2016)
Artículo / Artikulua,
We demonstrate tunable mid-infrared (MIR) beam steering devices based on multilayer graphene-dielectric metamaterials. The effective refractive index of such metamaterials can be manipulated by changing the chemical potential ...
Implementation of wireless sensor network architecture for interactive shopping carts to enable context-aware commercial areas
(IEEE, 2016)
Artículo / Artikulua,
An interactive shopping cart to enable context
aware environments within large commercial areas is presented.
A wireless sensor network was designed, with specific nodes
embedded within the shopping carts and infrastructure ...
Wide angle terahertz sensing with a cross-dipole frequency selective surface
(AIP Publishing, 2016)
Artículo / Artikulua,
In this work, a terahertz sensor based on a cross dipole frequency selective surface is analyzed and experimentally tested. The sensing structure is optimized for operation at the fundamental band- stop resonance near ...
Accurate circuit modeling of fishnet structures for negative-index-medium applications
(IEEE, 2016)
Artículo / Artikulua,
Metallic plates with a two-dimensional (2D) periodic distribution of sub-wavelength apertures are known to exhibit extraordinary transmission of electromagnetic waves. Stacking two or more of such plates gives place to the ...
Nanomaterials for functional textiles and fibers
(Springer US, 2015)
Artículo / Artikulua,
Nanoparticles are very interesting because of their surface properties, different from bulk materials. Such properties
make possible to endow ordinary products with new functionalities. Their relatively low cost with ...
Epsilon-near-zero metalenses operating in the visible
(Elsevier, 2016)
Artículo / Artikulua,
Several converging lenses working in the permittivity near to zero (ENZ) regime at optical frequencies are designed using an array of metal-dielectric-metal plasmonic waveguides. These plasmonic waveguides show a dispersive ...
Fiber optic sensor networks
(Elsevier, 2013)
info:eu-repo/semantics/article,
One of the main goals in fiber optic sensor technology is to multiplex together a high number of sensorsin the same network in order to share expensive terminal equipment and develop a system including multiple measuring ...
Random DFB fiber laser for remote (200 km) sensor monitoring using hybrid WDM/TDM
(IEEE, 2016)
info:eu-repo/semantics/article,
In this paper, a random distributed feedback fiber laser is proposed as a multiplexing scheme for ultralong range measurements (up to 200 km). Optical fiber sensors are time and wavelength multiplexed overcoming one of the ...
Simultaneous measurement of humidity and vibration based on a microwire sensor system using Fast Fourier Transform technique
(IEEE, 2016)
info:eu-repo/semantics/article,
This paper presents a new sensor system for vibration and relative humidity measurements based on its interaction with the evanescent field of a microwire. The interrogation of the sensing head is carried out by monitoring ...
Development of advanced structures for optical fiber lasers and sensors
(2015)
Tesis doctoral / Doktoretza tesia,
Desde la irrupción de la fibra óptica en las telecomunicaciones, han surgido multitud de desarrollos basados en sus propiedades. Así, en las últimas décadas, la rápida evolución de los sistemas basados en fibra óptica, así ...
