Experimental realization of an epsilon-near-zero graded-index metalens at terahertz frequencies
(American Physical Society, 2017)
Artículo / Artikulua,
The terahertz band has been historically hindered by the lack of efficient generators and detectors, but a series of recent breakthroughs have helped to effectively close the “terahertz gap.” A rapid development of terahertz ...
Blind spot mitigation in phased array antenna using metamaterials
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, a metaradome based on a fakir’s bed
of nails is designed and tested in order to suppress the blind
directions of a 100-element antenna array. The antenna is a
microstrip array designed to operate in X-band. ...
Advanced metamaterials for high resolution focusing and invisibility cloaks
(2016)
Tesis doctoral / Doktoretza tesia,
Los metamateriales, descendientes de los dieléctricos artificiales, tienen parámetros electromagnéticos inusuales y proporcionan más posibilidades que los dieléctricos naturales para el control de la propagación de la luz. ...
Nonbianisotropic complementary split ring resonators as angular selective metasurfaces
(Optical Society of America, 2017)
Artículo / Artikulua,
In this work, a metasurface with unconventional angular performance and composed by a nonbianisotropic complementary split ring resonator (NB-CSRR) is analyzed numerically and experimentally. A numerical study comparing ...
Metamaterials and plasmonics applied to devices based on periodic structures at high frequencies: microwaves, terahertz and optical range
(2016)
Tesis doctoral / Doktoretza tesia,
Esta tesis muestra el trabajo de investigación desarollado bajo el programa de doctorado “tecnología de las comunicaciones” de la Universidad Pública de Navarra (UPNA), para el grado de Doctor (PhD) en Ingenieria de ...
Experimental demonstration of metamaterials application for mitigating scan blindness in phased array antennas
(EDP Sciences, 2016)
Artículo / Artikulua,
This paper presents two metamaterial-inspired solutions to mitigate the scan blindness effects in a phased array antenna. In the first solution, portions of a bed of nails are introduced in the radome to prevent the excitation ...
Metamaterials and extraordinary transmission structures applied to microwave, millimeter and terahertz waves devices
(2017)
Tesis doctoral / Doktoretza tesia,
Los metamateriales aparecen en los primeros años del siglo XXI como materiales artificiales
que presentan un comportamiento electromagnético de alguna manera exótico. Al mismo
tiempo, se descubre un nuevo fenómeno ...
Full three-dimensional isotropic transformation media
(IOP Publishing, 2014)
info:eu-repo/semantics/article,
We present a method that enables the implementation of full three-dimensional
(3D) transformation media with minimized anisotropy. It is based on a special
kind of shape-preserving mapping and a subsequent optimization ...
Tunable beam steering enabled by graphene metamaterials
(Optical Society of America, 2016)
Artículo / Artikulua,
We demonstrate tunable mid-infrared (MIR) beam steering devices based on multilayer graphene-dielectric metamaterials. The effective refractive index of such metamaterials can be manipulated by changing the chemical potential ...
Plasmonics and metamaterials at terahertz frequencies
(2014)
Tesis doctoral / Doktoretza tesia,
The research presented in this manuscript falls under the framework of metamaterials
and plasmonics. It is mainly focused on applications at terahertz (THz) frequencies, a
spectral band located between microwaves and ...
