Research on metamaterials for antenna applications
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
During the last 20 years a lot of attention has been paid to apply Electromagnetic Band Gap (EBG) technology
in different frequency ranges, from microwaves to optics. EBG technology is based on the use of periodic structures ...
EBG superstrate antenna for WAAS bands
(2008)
Contribución a congreso / Biltzarrerako ekarpena,
Multiband antennas can simplify considerably the complexity of receivers and transmitters,
reducing the size and the mass of the conventional configurations. On the other hand, applications with
high directivity requirements ...
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 ...
Broadband radar cross-section reduction using AMC technology
(IEEE, 2013)
Artículo / Artikulua,
This paper presents the design, fabrication and characterization of a planar broadband chessboard structure to reduce the radar cross-section (RCS) of an object. The chessboard like configuration is formed by combining two ...
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 ...
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 ...
Moisture content estimation models of flour matrices in the 67-110 GHz frequency range using a nondestructive and contactless monitoring system
(IEEE, 2023)
Artículo / Artikulua,
This work addresses the lack of moisture content estimation models for food products in the millimeter-wave frequency range and showcases the potential of this range for designing compact, cost-effective, and in-line food ...
Dispersion properties of an elliptical patch with cross shaped aperture for synchronized propagation of transverse magnetic and electric surface waves
(MDPI, 2018)
Artículo / Artikulua,
This paper presents a novel pixel geometry for the implementation of metasurfaces requiring synchronized phase propagation of transverse magnetic (TM) and transverse electric (TE) modes. The pixel is composed by an elliptical ...
Remote sensing for plant water content monitoring: a review
(MDPI, 2021)
info:eu-repo/semantics/article,
Las redes sociales se han convertido en una de las principales fuentes de información, especialmente entre los más jóvenes. Al mismo tiempo, se ha incrementado la producción y circulación de información falsa o fake news ...
A water content continuous monitoring of grapevine xylem tissue using a portable low-power cost-effective FMCW radar
(IEEE, 2019)
Artículo / Artikulua,
This paper presents the real-time monitoring of a grapevine’s water content that flows up through the xylem tissue by means of a frequency-modulated continuous-wave (FMCW) radar. The application of an optimization process, ...
