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 ...
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) ...
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 ...
Mechanical 144GHz beam steering with all-metallic epsilon-near-zero lens antenna
(AIP Publishing, 2014)
Artículo / Artikulua,
An all-metallic steerable beam antenna composed of an ε-near-zero (ENZ) metamaterial lens is experimentally demonstrated at 144 GHz (λ0 = 2.083 mm). The ENZ lens is realized by an array of narrow hollow rectangular waveguides ...
Terahertz epsilon-near-zero graded-index lens
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
An epsilon-near-zero graded-index converging lens with planar
faces is proposed and analyzed. Each perfectly-electric conducting (PEC)
waveguide comprising the lens operates slightly above its cut-off frequency
and has ...
Low profile THz periodic leaky-wave antenna
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, a 0.566THz flat leaky-wave antenna, consisting of a central λ0/2 slot surrounded by straight parallel wedge corrugations, is numerically and experimentally analyzed. Simulations show a moderately high gain ...
All-metallic ε-near-zero (ENZ) lens based on ultra-narrow hollow rectangular waveguides: experimental results
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Here we perform numerical and experimental investigation of plano-concave all-metallic ε-near-zero (ENZ) lens with operational frequency f = 144 GHz. The ENZ lens is achieved by stacking an array of narrow hollow rectangular ...
Focus on terahertz plasmonics
(IOP Publishing, 2015)
info:eu-repo/semantics/article,
Plasmonics is one of the growing fields in modern photonics that has garnered increasing interest over
the last few years. In this focus issue, the specific challenges concerning terahertz plasmonics have
been addressed ...
Polarization-tunable negative or positive refraction in self-complementariness-based extraordinary transmission prism
(EMW Publishing, 2010)
Artículo / Artikulua,
Here we report a prism made of stacked quasi-selfcomplementary extraordinary transmission surfaces which allows simultaneously left- and right-handed propagation within the V-band for vertical and horizontal polarizations, ...
Electromagnetic response of extraordinary transmission plates inspired on Babinet’s principle
(InTech, 2011)
Capítulo de libro / Liburuen kapitulua,
This chapter is devoted to polarization effects arisen from perforated metallic plates
exhibiting extraordinary transmission (ET). Setting aside the state-of-the-art of perforated
metallic plates, we show that by applying ...
