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 ...
Terahertz carpet cloak based on a ring resonator metasurface
(American Physical Society, 2015)
info:eu-repo/semantics/article,
In this work we present the concept and design of an ultrathin (λ/22) terahertz (THz) unidirectional carpet cloak based on the local phase compensation approach enabled by gradient metasurfaces. A triangular surface bump ...
Compact dual-band terahertz quarter-wave plate metasurface
(IEEE, 2014)
info:eu-repo/semantics/article,
A dual-band quarter-wave plate based on a modified extraordinary transmission hole array is numerically analyzed and experimentally demonstrated at terahertz frequencies. To control independently orthogonal polarizations, ...
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 ...
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) ...
Zoned near-zero refractive index fishnet lens antenna: steering millimeter waves
(AIP Publishing, 2014)
Artículo / Artikulua,
A zoned fishnet metamaterial lens is designed, fabricated, and experimentally demonstrated at millimeter wavelengths to work as a negative near-zero refractive index lens suitable for compact lens antenna configurations. ...
Localized photonic jets from flat, three-dimensional dielectric cuboids in reflection mode
(Optical Society of America, 2015)
Artículo / Artikulua,
A photonic jet (a terajet at terahertz frequencies) commonly denotes a specific, spatially localized region in the near field on the front side of a dielectric particle with a diameter comparable with the wavelength ...
