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 ...
Electroinductive waves in chain of complementary metamaterial elements
(AIP Publishing, 2006) Artículo / Artikulua,
Electronductive waves supported by chains of resonators drilled on a metallic plate are presented. Propagation of energy comes as a consequence of the electric coupling between these resonators. Therefore, these waves ...
Blind spot mitigation in phased array antenna using metamaterials
(IEEE, 2014) Contribución a congreso / Biltzarrerako ekarpena,
In this work, a metaradome based on a fakir’s bed of nails is designed and tested in order to suppress the blind directions of a 100-element antenna array. The antenna is a microstrip array designed to operate in X-band. ...
Experimental demonstration of metamaterials application for mitigating scan blindness in phased array antennas
(EDP Sciences, 2016) Artículo / Artikulua,
This paper presents two metamaterial-inspired solutions to mitigate the scan blindness effects in a phased array antenna. In the ﬁrst solution, portions of a bed of nails are introduced in the radome to prevent the excitation ...
Lensing system and Fourier transformation using epsilon-near-zero metamaterials
(American Physical Society, 2012) info:eu-repo/semantics/article,
Metamaterials and metastructures with effective relative permittivity near zero exhibit unusual wave properties such as uniform phase distributions across such domains. Here we discuss the possibility of using ε-near-zero ...
