Dual circularly polarized broadside beam metasurface antenna
(IEEE, 2016)
Artículo / Artikulua,
This paper presents the design of a modulated metasurface (MTS) antenna capable to provide both righthand (RH) and left-hand (LH) circularly polarized (CP) boresight
radiation at Ku-band (13.5 GHz). This antenna is based ...
Intelligent vehicle communication: deterministic propagation prediction in transportation systems
(IEEE, 2016)
Artículo / Artikulua,
Intelligent Transportation Systems (ITS) are currently under
intense research and development for making transportation safer and
more efficient. The development of such vehicular communication
systems requires accurate ...
Fabrication of Bragg gratings on the end facet of standard optical fibers by sputtering the same material
(IEEE, 2016)
Artículo / Artikulua,
A sputtering process has been applied to deposit quarter-wavelength stacks on the end facet of cleaved optical fibers by using only one sputtering target. Standard multimode optical fibers were used as substrates to fabricate ...
Arc-induced long period fiber gratings in the dispersion turning points
(IEEEOptical Society of America, 2016)
Artículo / Artikulua,
We demonstrated the possibility to inscribe longperiod
fiber gratings (LPFGs) in a B/Ge codoped fiber by using
grating periods shorter than 150 μm. We also have arc-induced
in the SMF 28 fiber an LPFG in the dispersion ...
Sensitivity optimization with cladding-etched long period fiber gratings at the dispersion turning point
(Optical Society of America, 2016)
Artículo / Artikulua,
This work presents a refractive index sensor based on a long period fiber grating
(LPFG) made in a reduced cladding fiber whose low order cladding modes have the turning
point at large wavelengths. The combination of ...
Giant sensitivity of optical fiber sensors by means of lossy moderesonance
(Elsevier, 2016)
Artículo / Artikulua,
Here we show an optical refractometer with a giant sensitivity of 304,360 nm per refractive index unit(nm/RIU). This sensitivity corresponds to a resolution of 3.28 × 10−9RIU if a standard optical spectrumanalyzer with a ...
Etched LPFGs in reflective configuration for sensitivity and attenuation band depth increase
(IEEE, 2016)
Artículo / Artikulua,
A reflection configuration setup for long-period
fiber gratings is presented. It permits to obtain a unique band
with attenuation double than that obtained in transmission
configuration, which is interesting for ...
An optimized method based on digitalized Lissajous curve to determine lifetime of luminescent materials on optical fiber sensors
(Hindawi, 2016)
Artículo / Artikulua,
A method is proposed to determine lifetime of luminescent emissions based on the phase shift measurement employing the digitalized Lissajous representation: this diagram has been typically used with analogical algorithms, ...
Novel highly sensitive protein sensors based on tapered optical fibres modified with Au-based nanocoatings
(Hindawi Publishing Corporation, 2016)
Artículo / Artikulua,
Novel protein sensors based on tapered optical fibres modified with Au coatings deposited using two different procedures
are proposed. Au-based coatings are deposited onto a nonadiabatic tapered optical fibre using (i) a ...
Astronomical component estimation (ACE v.1) by time-variant sinusoidal modeling
(Copernicus Publications, 2016)
info:eu-repo/semantics/article,
Accurately deciphering periodic variations in paleoclimate proxy signals is essential for cyclostratigraphy. Classical spectral analysis often relies on methods based on (fast) Fourier transformation. This technique has ...
