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 ...
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, ...
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 ...
Gain improvement of dual band antenna based on complementary rectangular split-ring resonator
(Hindawi / Wiley, 2012)
info:eu-repo/semantics/article,
A simple and successful dual band patch linear polarized rectangular antenna design is presented. The dual band antenna is
designed etching a complementary rectangular split-ring resonator in the patch of a conventional ...
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 ...
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 ...
Millimeter-wave phase resonances in compound reflection gratings with subwavelength grooves
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
Experimental evidence of phase resonances in a dual-period
reflection structure comprising three subwavelength grooves in each
period is provided in the millimeter-wave regime. We have analyzed and
measured the response ...
Experimental demonstration of a millimeter-wave metallic ENZ lens based on the energy squeezing principle
(IEEE, 2015)
info:eu-repo/semantics/article,
The performance of an epsilon-near zero (ENZ) plano-concave lens is experimentally demonstrated and verified at the D-band of the millimeter-waves. The lens is comprised of an array of narrow metallic waveguides near cut-off ...
