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 ...
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 ...
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 ...
3D-printed 96 GHz bull’s-eye antenna with off-axis beaming
(IEEE, 2017)
Artículo / Artikulua,
Reducing the profile, footprint and weight of antennas embarked on aircrafts, drones or satellites has been a long pursued objective. Here we tackle this issue by developing a millimeter-wave 96 GHz elliptical Bull’s-Eye ...
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, ...
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 ...
