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 ...
Terajets produced by dielectric cuboids
(AIP Publishing, 2014)
Artículo / Artikulua,
The capability of generating terajets using three-dimensional (3D) dielectric cuboids working at terahertz (THZ) frequencies (as analogues of nanojets in the infrared band) is introduced and studied numerically. The focusing ...
ε-near-zero (ENZ) graded index quasi-optical devices: steering and splitting millimeter waves
(IOP Publishing, 2014)
Artículo / Artikulua,
Graded index ε near-zero (GRIN-ENZ) quasi-optical components such as beam steerers and power splitters are designed, simulated and analyzed. The GRIN-ENZ medium is realized using stacked narrow hollow waveguides whose ...
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 ...
Impact of high power interference sources in planning and deployment of wireless sensor networks and devices in the 2.4 GHz frequency band in heterogeneous environments
(MDPI, 2012)
Artículo / Artikulua,
In this work, the impact of radiofrequency radiation leakage from microwave ovens and its effect on 802.15.4 ZigBee-compliant wireless sensor networks operating in the 2.4 GHz Industrial Scientific Medical (ISM) band is ...
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 ...
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 ...
Comportamiento de propagacion electromagnetica en el apilamiento de agujeros sublambda y agujeros propagantes
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, we provide more insight on the physics
underlying the transmission through subwavelength hole arrays
metaprism by comparing it with propagating hole arrays prism.
We show the critical role that the size ...
Lentes metálicas basadas en el fenómeno de transmisión extraordinaria para conseguir índices de refracción negativos
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this communication we report plano-concave
and bi-concave metamaterial lenses based on the close stack of
subwavelegnth hole arrays. Contrary to what is expected from
cut-off holes, an engineered array of holes ...
