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 ...
Experimental realization of an epsilon-near-zero graded-index metalens at terahertz frequencies
(American Physical Society, 2017)
Artículo / Artikulua,
The terahertz band has been historically hindered by the lack of efficient generators and detectors, but a series of recent breakthroughs have helped to effectively close the “terahertz gap.” A rapid development of terahertz ...
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. ...
Metamaterials and extraordinary transmission structures applied to microwave, millimeter and terahertz waves devices
(2017)
Tesis doctoral / Doktoretza tesia,
Los metamateriales aparecen en los primeros años del siglo XXI como materiales artificiales
que presentan un comportamiento electromagnético de alguna manera exótico. Al mismo
tiempo, se descubre un nuevo fenómeno ...
Full three-dimensional isotropic transformation media
(IOP Publishing, 2014)
info:eu-repo/semantics/article,
We present a method that enables the implementation of full three-dimensional
(3D) transformation media with minimized anisotropy. It is based on a special
kind of shape-preserving mapping and a subsequent optimization ...
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 ...
