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 ...
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 ...
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 ...
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 ...
Circuit approach to the minimal configuration of terahertz anomalous extraordinary transmission
(American Institute of Physics, 2011)
Artículo / Artikulua,
In this letter we present an in-depth circuit analysis of anomalous extraordinary transmission ET
through subwavelength slit and hole arrrays loaded by a dielectric slab. We show the key role played
by the thickness of the ...
Analysis of surface-plasmon-like modes under an engineering perspective
(2011)
Contribución a congreso / Biltzarrerako ekarpena,
In this communication we show how one can exploit equivalent circuits to analyze surface-plasmon-like modes (slit and hole arrays, Sievenpiper mushrooms and coaxial hole arrays) and to propose new designs with outstanding ...
New regimes to achieve enhanced transmission through subwavelength hole arrays
(2011)
Contribución a congreso / Biltzarrerako ekarpena,
In this communication we present millimetre- and THz-waves experimental confirmation of enhanced
transmission through subwavelength hole arrays with rectangular lattice when the incident electric field is parallel to ...
The beauty of anisotropy in extraordinary transmission fishnet metamaterials
(2011)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, we explore both numerically and experimentally, the possibility to obtain positive and negative refraction regimes that depend on the wave polarization, exploiting the strong anisotropy of extraordinary ...
Generación del modo HE11 a partir de una guía circular lisa monomodo
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present an original taper design to obtain the HE11 corrugated circular waveguide
mode exciting with a pure TE11 monomode smooth circular waveguide mode.
The proposed corrugated taper has a longitudinal ...
