A slow light fishnet-like absorber in the millimeter-wave range
(EMW Publishing, 2011)
Artículo / Artikulua,
A novel route to achieve a narrowband free-space electromagnetic absorber in any range of the spectrum based on stacked subwavelength hole arrays is proposed. The absorption is obtained by means of a slow light mode inside ...
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 ...
Hedgehog subwavelength hole arrays: control over the THz enhanced transmission
(Institute of Physics Publishing, 2013)
Artículo / Artikulua,
By backing or sandwiching a holey metal layer with or between isotropic dielectric slabs, additional peaks of transmission within the long-wavelength regime arise as a result of the induced transverse magnetic (TM) or ...
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 ...
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 ...
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 ...
Meta-material behaviour of the new Coherently Radiating Periodic Structures (CORPS)
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the study of the new Coherently Radiating Periodic Structures (CORPS) like a Metamaterial
sets out. The shape of the structure under study is composed by two different layers, one layer is
an array of ...
Desfasadores para microstrip empleando metamateriales
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper an application of LH materials at
microwave frequencies (10GHz) is presented. A compact
quarter-wave impedance transformer is proposed using
alternating sections of left handed media (LHM) and
conventional ...
Design of a planar meta-surface based on dipoles and wires for antenna applications
(2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the design of a planar meta-surface based
on dipoles and wires is presented. The unit cell is formed
by three independent layers, which contain two parallel
dipoles and one wire. The behaviour of these ...
