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 ...
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 ...
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 ...
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. ...
Nonbianisotropic complementary split ring resonators as angular selective metasurfaces
(Optical Society of America, 2017) Artículo / Artikulua,
In this work, a metasurface with unconventional angular performance and composed by a nonbianisotropic complementary split ring resonator (NB-CSRR) is analyzed numerically and experimentally. A numerical study comparing ...
