Optimized strain long-period fiber grating (LPFG) sensors operating at the dispersion turning point
(IEEE, 2018)
Artículo / Artikulua,
Two phenomena for enhancing the sensitivity of longperiod
fiber gratings are combined toward an increase of the sensitivity
to strain of this type of devices: the dispersion turning point
(DTP) and the cladding diameter ...
Sensitivity enhancement experimental demonstration using a low cutoff wavelength SMS modified structure coated with a pH sensitive film
(Elsevier, 2018)
Artículo / Artikulua,
The multimode interference (MMI) effect in a single mode-multimode-single mode (SMS) can be used fordevelopment of wavelength shift detection based sensors. In this work, the focus is centered on obtainingwavelength shifts ...
Nanofabrication of phase-shifted Bragg gratings on the end facet of multimode fiber towards development of optical filters and sensors
(Elsevier, 2018)
Artículo / Artikulua,
This work describes the process of nanofabrication of phase-shifted Bragg gratings on the end facet of a
multimode optical fiber with a pulsed DC sputtering system based on a single target. Several structures
have been ...
Label-free wavelength and phase detection based SMS fiber immunosensors optimized with cladding etching
(Elsevier, 2018)
Artículo / Artikulua,
The performance of E-SMS (Etched Singlemode-Multimode-Singlemode) optical fiber structures as immunosensors has been assessed by the implementation of antibody/antigen immunoassays. Through this procedure
it has been ...
Long period fiber grating for biosensing: an improved design methodology to enhance add-layer sensitivity
(IEEE, 2018)
Artículo / Artikulua,
We present our theoretical study on the design of
LPFG sensor where its add-layer sensitivity is enhanced. addlayer
sensitivity quantifies the sensitivity of the sensor to the
changes taking place within few tens of ...
Rectangular waveguide filters with meandered topology
(IEEE, 2018)
Artículo / Artikulua,
In this paper, a new topology for rectangular
waveguide bandpass and low-pass filters is presented. A simple,
accurate, and robust design technique for these novel meandered
waveguide filters is provided. The proposed ...
Ku band low profile asymmetric Bull’s-Eye antenna with reduced side lobes and monopole feeding
(IEEE, 2018)
Artículo / Artikulua,
In this paper, a linearly polarized low profile and asymmetric Bull’s-Eye leaky wave antenna fed by a monopole operating at 13 GHz is presented. Broadside radiation from the monopole is achieved by surrounding it with an ...
Comparison between capacitive and microstructured optical fiber soil moisture sensors
(MDPI, 2018)
Artículo / Artikulua,
Soil moisture content has always been an important parameter to control because it is a
deterministic factor for site-specific irrigation, seeding, transplanting, and compaction detection.
In this work, a discrete sensor ...
Experimental validation of a Ku-band dual circularly polarized metasurface antenna
(IEEE, 2018)
Artículo / Artikulua,
The experimental validation of a Ku-band dual circularly polarized (CP) broadside-beam metasurface (MTS) antenna is presented. A radially modulated anisotropic single layer MTS has been synthesised employing sub-wavelength ...
Ultra-long (290 km) remote interrogation sensor network based on a random distributed feedback fiber laser
(Optical Society of America, 2018)
info:eu-repo/semantics/article,
In this work, an interferometric sensor has been interrogated 290 km away from the
monitoring station, reaching the longest distance in fiber optic sensing up to date. This has been
attained by employing a double-pumped ...
