Hedgehog subwavelength hole arrays: control over the THz enhanced transmission
(Institute of Physics Publishing, 2013)
Artículo / Artikulua,
By backing or sandwiching a holey metal layer with or between isotropic dielectric slabs, additional peaks of transmission within the long-wavelength regime arise as a result of the induced transverse magnetic (TM) or ...
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 ...
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, ...
Ultra-wideband metamaterial filter based on electroinductive-wave coupling between microstrips
(EMW Publishing, 2009)
Artículo / Artikulua,
In this work, we analyse the frequency response of
microstrip lines coupled by complementary split ring resonators
(CSRRs) etched on the ground plane supporting electroinductive
waves (EIWs). The single-particle ...
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 ...
One-way quasiplanar terahertz absorbers using nonstructured polar dielectric layers
(American Physical Society, 2017)
Artículo / Artikulua,
A concept of quasiplanar one-way transparent terahertz absorbers made of linear isotropic materials is presented. The resulting structure consists of a homogeneous absorbing layer of polar dielectric, GaAs, a dispersion-free ...
Exploiting the dispersion of the double-negative-index fishnet metamaterial to create a broadband low-profile metallic lens
(Optical Society of America, 2015)
info:eu-repo/semantics/article,
Metamaterial lenses with close values of permittivity and
permeability usually display low reflection losses at the expense of narrow
single frequency operation. Here, a broadband low-profile lens is designed
by exploiting ...
Regular and anomalous extraordinary optical transmission at the THz-gap
(Optical Society of America, 2009)
info:eu-repo/semantics/article,
In this paper Anomalous Extraordinary Transmission (ET) is
reported for s-polarization of low loss doubly periodic subwavelength hole
arrays patterned on polypropylene (PP) substrates by conventional contact
photolithography ...
Left-handed extraordinary optical transmission through a photonic crystal of subwavelength hole arrays
(Optical Society of America, 2006)
info:eu-repo/semantics/article,
Metamaterial structures are artificial materials that show
unconventional electromagnetic properties such as photonic band-gap,
extraordinary optical transmission and left-handed propagation. Up to now,
relations of photonic ...
