Resultados experimentales de la mejora de potencia radiada por un dipolo mediante un superstrato left-handed
(2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a comparison between the measured
radiation performances of a single dipole and a dipole with
a left handed superstrate based on a finite periodic repetition
of a unit cell is presented. First of all the ...
A gap waveguide fed circular polarization antennas in the millimeter wave range
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
In this work, a novel circular polarization (CP) antennas in ridge gap waveguide (RGW) working in the V-band of the millimeter-wave spectrum is presented. CP is generated in a simple and effective way by means of two ...
Circuit and multipolar approaches to investigate the balance of powers in 2D scattering problems
(EMW Publishing, 2013)
Artículo / Artikulua,
Circuit and multipolar approaches are presented to investigate the correlation between absorption and scattering processes in 2D problems. This investigation was inspired by earlier works of Prof.R.E. Collin, which pointed ...
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 ...
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 ...
Fe-rich ferromagnetic wires for self-sensing materials
(IEEE, 2012)
Artículo / Artikulua,
The possibility of using Fe-rich wires in mechanical stress self-sensing materials is investigated. To this end, a retrieval technique aimed to characterize the high-frequency magnetoimpedance effect in ferromagnetic wires ...
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, ...
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 ...
300 GHz optoelectronic transmitter combining integrated photonics and electronic multipliers for wireless communication
(MDPI, 2019)
info:eu-repo/semantics/article,
THz communications systems at carrier frequencies above 200 GHz are the key to enable next-generation mobile communication networks with 100 Gbit/s wireless data rates. One of the key questions is, which carrier frequency ...
