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 ...
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) ...
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 ...
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 ...
Wood zone plate fishnet metalens
(EDP Sciences, 2015)
Artículo / Artikulua,
Fresnel-zone plate lenses provide focusing performance while having low profile. Unfortunately, they usually display higher reflection losses than conventional dielectric lenses. Here, we demonstrate a low-profile Wood ...
Broadband frequency and angular response of a sinusoidal bull’s eye antenna
(IOP Publishing, 2016)
Artículo / Artikulua,
A thorough experimental study of the frequency and beaming angle response of a metallic
leaky-wave bull’s eye antenna working at 77 GHz with a sinusoidally corrugated profile
is presented. The beam scanning property of ...
Ultra-compact planoconcave zoned metallic lens based on the fishnet metamaterial
(AIP Publishing, 2013)
Artículo / Artikulua,
A 1.5λ0 -thick planoconcave zoned lens based on the fishnet metamaterial is demonstrated experimentally at millimeter wavelengths. The zoning technique applied allows a volume reduction of 60% compared to a full fishnet ...
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 ...
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. ...
Zoned fishnet lens antenna with reference phase for side lobe reduction
(IEEE, 2015)
Artículo / Artikulua,
Reduction of first side lobe level and nulls in artificial fishnet metalenses is accomplished here by applying the reference phase concept along with the zoning technique. Higher focusing efficiency is achieved for a ...
