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 ...
Wide angle terahertz sensing with a cross-dipole frequency selective surface
(AIP Publishing, 2016)
Artículo / Artikulua,
In this work, a terahertz sensor based on a cross dipole frequency selective surface is analyzed and experimentally tested. The sensing structure is optimized for operation at the fundamental band- stop resonance near ...
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 ...
Labyrinth metasurface absorber for ultra-high-sensitivity terahertz thin film sensing
(Wiley, 2018)
Artículo / Artikulua,
In this work, a labyrinth metasurface sensor operating at the low‐frequency edge of the THz band is presented. Its intricate shape leads to a high electric field confinement on the surface of the structure, resulting in ...
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 ...
Frozen mode from hybridized extraordinary transmission and Fabry-Perot resonances
(American Physical Society, 2013)
info:eu-repo/semantics/article,
Frozen modes arising in stacked subwavelength hole arrays are studied in detail. Their origin is proved to be connected with the interaction between the extraordinary transmission resonance and the Fabry–Perot cavity mode. ...
Wideband unidirectional transmission with tunable sign-switchable refraction and deflection in nonsymmetric structures
(American Physical Society, 2013)
info:eu-repo/semantics/article,
A general theory of reciprocal unidirectional transmission with tunable sign-switchable refraction and deflection of outgoing wave in structures with broken spatial inversion symmetry is presented. Several coupling scenarios ...
THz sensing with anomalous extraordinary optical transmission hole arrays
(MDPI, 2018)
Artículo / Artikulua,
Subwavelength hole array (HA) metasurfaces support the so-called extraordinary optical transmission (EOT) resonance that has already been exploited for sensing. In this work, we demonstrate the superior performance of a ...
On the performance of an ENZ-based sensor using transmission line theory and effective medium approach
(IOP Publishing, 2019)
Artículo / Artikulua,
In this paper we perform an in-depth theoretical studyofa sensing platform based on epsilon-near- zero (ENZ) metamaterials. The structure proposed for sensing is a narrow metallic waveguide channel. An equivalent circuit ...
