Study on isolation improvement between closely-packed patch antenna arrays based on fractal metamaterial electromagnetic bandgap structures
(Institution of Engineering and Technology, 2018)
info:eu-repo/semantics/article,
A decoupling metamaterial (MTM) configuration based on fractal electromagnetic-bandgap (EMBG) structure is shown to significantly enhance isolation between transmitting and receiving antenna elements in a closely-packed ...
Study on antenna mutual coupling suppression using integrated metasurface isolator for SAR and MIMO applications
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
A metasurface based decoupling structure that is composed of a square-wave slot pattern with exaggerated corners that is implemented on a rectangular microstrip provides high-isolation between adjacent patch antennas for ...
Mutual-coupling reduction in metamaterial substrate integrated waveguide slotted antenna arrays using metal fence isolators for SAR and MIMO applications
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
A new type of mutual coupling reduction technique is applied to metamaterial substrate integrated waveguide (SIW) slotted antenna array. The circular shaped reference SIW antenna array is constructed from Alumina substrate ...
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 ...
Optical power-based interrogation of plasmonic tilted fiber Bragg grating biosensors
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
Two interrogation techniques for plasmonic tilted fiber Bragg grating sensors are reported and experimentally tested. Typical interrogation methods are usually based on tracking the wavelength shift of the most sensitive ...
Polyaniline deposition on tilted fiber Bragg grating for pH sensing
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
In this paper, we present the results of a new pH sensor based on a polyaniline (PAni) coating on the surface of a tilted fiber Bragg grating. The pH-sensitive PAni was deposited by in situ chemical oxidative polymerization. ...
Tree-to-tree competition in mixed European beech-Scots pine forests has different impacts on growth and water-use efficiency depending on site condition.
(WileyBritish Ecological Society, 2018)
Artículo / Artikulua,
Mixed conifer-hardwood forests can be more productive than pure forests and they are increasingly considered as ecosystems that could provide adaptation strategies in the face of global ...
Chemical and mechanical stability of air annealed cathodic arc evaporated CrAlON coatings
(Elsevier, 2018)
info:eu-repo/semantics/article,
This study reports the synthesis and characterization of ternary Cr-Al-O and quaternary Cr-Al-O-N coatings deposited by cathodic arc physical vapour deposition, for various nitrogen and oxygen mass flow ratios during the ...
CrAlON CAE-PVD coatings for oxidation and wear protection of TZM alloys in FAST sintering applications
(Elsevier, 2018)
info:eu-repo/semantics/article,
In this work CrAlO and CrAlO/CrAlN multilayers deposited by cathodic arc evaporation are evaluated as protective films in metal and ceramic powder FAST sintering tool dies fabricated in titanium-zirconium-molybdenum allows ...
Consensus image method for unknown noise removal
(Elsevier, 2014)
info:eu-repo/semantics/article,
Noise removal has been, and it is nowadays, an important task in computer vision. Usually, it is a previous task preceding other tasks, as segmentation or reconstruction. However, for most existing denoising algorithms the ...
