3D-printed 96 GHz bull’s-eye antenna with off-axis beaming
(IEEE, 2017)
Artículo / Artikulua,
Reducing the profile, footprint and weight of antennas embarked on aircrafts, drones or satellites has been a long pursued objective. Here we tackle this issue by developing a millimeter-wave 96 GHz elliptical Bull’s-Eye ...
Negative refraction through an extraordinary transmission left-handed metamaterial slab
(American Physical Society, 2009)
Artículo / Artikulua,
In this work we present numerical and experimental results of negative refraction through a negative index
metamaterial based on miniaturized extraordinary transmission stacked subwavelength hole arrays, also known
as ...
Polarization selection with stacked hole array metamaterial
(AIP Publishing, 2008)
Artículo / Artikulua,
Polarization rotation or selection appears in materials with optical activity, or those with Faraday
effect, or in liquid crystals. In this letter we present a structure, with an analogous response, using
stacked ...
Converging biconcave metallic lens by double-negative extraordinary transmission metamaterial
(AIP Publishing, 2009)
Artículo / Artikulua,
In this letter we present simulation and experimental results of a left-handed converging biconcave
metallic lens made of stacked subwavelength hole arrays SSHAs working in the millimeter wave
range with additional ...
Experimental demonstration of phase resonances in metallic compound gratings with subwavelength slits in the millimeter wave regime
(AIP Publishing, 2009)
Artículo / Artikulua,
We provide experimental evidence of phase resonances in metallic periodic structures in which each
period comprises several subwavelength slits of the same width. We have analyzed and measured
the response of these ...
Mid-infrared plasmonic inductors: enhancing inductance with meandering lines
(Nature Publishing Group, 2014)
Artículo / Artikulua,
We present a mid-infrared inductor that when applied to an extraordinary transmission hole array produces a strong redshift of the resonant peak accompanied by an unprecedented enlargement of the operation bandwidth. The ...
Broadband frequency and angular response of a sinusoidal bull’s eye antenna
(IOP Publishing, 2016)
Artículo / Artikulua,
A thorough experimental study of the frequency and beaming angle response of a metallic
leaky-wave bull’s eye antenna working at 77 GHz with a sinusoidally corrugated profile
is presented. The beam scanning property of ...
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 ...
Strong lateral displacement in polarization anisotropic extraordinary transmission metamaterial
(IOP Publishing Ltd, 2010)
Artículo / Artikulua,
In this paper, a deep numerical as well as experimental study of the anisotropy response of extraordinary transmission metamaterials constructed by stacking subwavelength hole arrays is presented. Two-dimensional (2D) ...
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 ...
