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 ...
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, ...
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 ...
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 ...
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 ...
Lensing system and Fourier transformation using epsilon-near-zero metamaterials
(American Physical Society, 2012)
info:eu-repo/semantics/article,
Metamaterials and metastructures with effective relative permittivity near zero exhibit unusual wave properties such as uniform phase distributions across such domains. Here we discuss the possibility of using ε-near-zero ...
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 spectroscopy (MIR) for simultaneous determination of fat and protein content in meat of several animal species
(Springer, 2017)
Artículo / Artikulua,
The aim of this research was to study the application of MIR spectroscopy as an alternative to conventional methods to determine fat and protein content. Samples of the main species used to produce meat products were ...
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 ...
