Arrangements of via-holes in microstrip lines as metallodielectric periodic structures
(Wiley, 2000)
Artículo / Artikulua,
In this paper, the use of via holes in microstrip lines to design periodic structures that can be regarded as metallodielectric electromagnetic crystals is analyzed. The proposed novel periodic structures achieve a notably ...
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 ...
On the determination of the phase center of gaussian horn antennas
(1998)
Contribución a congreso / Biltzarrerako ekarpena,
Gaussian horn antenna designs have experimentally demonstrated excellent performance to produce a very pure Gaussian beam mode with extremely low sidelobes and crosspolarization levels. These results make very attractive ...
Generation of the HE11 mode in rectangular waveguide using gaussian techniques
(IEEE, 1999)
Contribución a congreso / Biltzarrerako ekarpena,
A new and efficient design of a rectangular corrugated waveguide mode converter,
from TE10 mode in a smooth rectangular monomode waveguide to HE11 mode in a
corrugated rectangular waveguide, is proposed. The main idea ...
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 ...
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 ...
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 ...
