Remote (250 km) fiber Bragg grating multiplexing system
(MDPI, 2011)
Artículo / Artikulua,
We propose and demonstrate two ultra-long range fiber Bragg grating (FBG) sensor interrogation systems. In the first approach four FBGs are located 200 km from the monitoring station and a signal to noise ratio of 20 dB ...
A slow light fishnet-like absorber in the millimeter-wave range
(EMW Publishing, 2011)
Artículo / Artikulua,
A novel route to achieve a narrowband free-space electromagnetic absorber in any range of the spectrum based on stacked subwavelength hole arrays is proposed. The absorption is obtained by means of a slow light mode inside ...
An antibacterial coating based on a polymer/sol-gel hybrid matrix loaded with silver nanoparticles
(Springer, 2011)
Artículo / Artikulua,
In this work a novel antibacterial surface composed of an organic-inorganic hybrid matrix of tetraorthosilicate and a polyelectrolyte is presented. A precursor solution of tetraethoxysilane (TEOS) and poly(acrylic acid ...
Resolution capabilities of future THz cameras
(Radioengineering Society, 2011)
Artículo / Artikulua,
THz technology for developing imaging systems
has recently aroused great interest, mainly due to the large
number of applications in which these frequencies can be
used: security, vision in hard environments, etc.

Circuit approach to the minimal configuration of terahertz anomalous extraordinary transmission
(American Institute of Physics, 2011)
Artículo / Artikulua,
In this letter we present an in-depth circuit analysis of anomalous extraordinary transmission ET
through subwavelength slit and hole arrrays loaded by a dielectric slab. We show the key role played
by the thickness of the ...
Design of concentric ring antenna arrays for isoflux radiation in GEO satellites
(Institute of Electronics, Information and Communication Engineers (IEICE), 2011)
Artículo / Artikulua,
The design of concentric rings arrays for isoflux radiation is reported in this paper. This design considers the reduction of the side lobe level and the isoflux radiation requirements for Geostationary Earth Orbit (GEO) ...
Surface waves of finite size electromagnetic band gap woodpile structures
(EMW Publishing, 2011)
Artículo / Artikulua,
This paper studies the surface modes at the interface of finite size Electromagnetic Band Gap (EBG) woodpile structures. The impact of different types of woodpile terminations on the properties of these surface modes is ...
Simplifying the feeding network for multi-beam circular antenna arrays by using corps
(EMW Publishing, 2011)
Artículo / Artikulua,
An innovative way to analyze the design of beam-forming networks (BFN) for scannable multi-beam circular antenna arrays using the CORPS (Coherently Radiating Periodic Structures) concept is introduced. This design of ...
Láseres de fibra óptica

Desde su desarrollo en los años 60 hasta nuestros días, los láseres de fibra óptica
han ido incrementando su importancia en diversos ámbitos de nuestra vida. Ya sea
en la medicina, la electrónica de consumo o la industria, ...
Influence of waist length in lossy mode resonances generated with coated tapered single mode optical fibers
(IEEE, 2011)
Artículo / Artikulua,
In this work, the generation of electromagnetic resonances due to the deposition of a nanocoating on a tapered single-mode optical fiber is analyzed. The layer-by-layer technique is used to control the thickness of the ...
