Meta-material behaviour of the new Coherently Radiating Periodic Structures (CORPS)
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the study of the new Coherently Radiating Periodic Structures (CORPS) like a Metamaterial
sets out. The shape of the structure under study is composed by two different layers, one layer is
an array of ...
Desfasadores para microstrip empleando metamateriales
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper an application of LH materials at
microwave frequencies (10GHz) is presented. A compact
quarter-wave impedance transformer is proposed using
alternating sections of left handed media (LHM) and
conventional ...
Metamaterial inspired electromagnetic bandgap filter for ultra-wide stopband screening devices of electromagnetic interference
(Springer, 2023)
Artículo / Artikulua,
Presented here is a reactively loaded microstrip transmission line that exhibit an ultra-wide
bandgap. The reactive loading is periodically distributed along the transmission line, which is
electromagnetically coupled. ...
Plasmonics and metamaterials at terahertz frequencies
(2014)
Tesis doctoral / Doktoretza tesia,
The research presented in this manuscript falls under the framework of metamaterials
and plasmonics. It is mainly focused on applications at terahertz (THz) frequencies, a
spectral band located between microwaves and ...
Hyperbolic lens antenna in groove gap waveguide technology at sub-millimeter waves
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a flat hyperbolic lens antenna using Groove Gap Waveguide (GGW) technology is designed at 300 GHz. A GGW horn antenna is used to feed the metamaterial lens placed in a parallel plate waveguide (PPW), in order ...
Near-zero-index media as electromagnetic ideal fluids
(National Academy of Sciences, 2020)
info:eu-repo/semantics/article,
Near-zero-index (NZI) supercoupling, the transmission of electromagnetic waves inside a waveguide irrespective of its shape, is a counterintuitive wave effect that finds applications in optical interconnects and engineering ...
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 ...
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 ...
Shaping the quantum vacuum with anisotropic temporal boundaries
(De Gruyter, 2022)
Artículo / Artikulua,
Temporal metamaterials empower novel forms of wave manipulation with direct applications to quantum state transformations. In this work, we investigate vacuum amplification effects in anisotropic temporal boundaries. Our ...
