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 ...
Labyrinth absorber based on metageometries metasurface for fungi detection
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
In this paper a labyrinth metasurface based in the new paradigm of metageometries is designed to operate in the Terahertz (THz) band as a biosensor. First, a numerical study is carried out to study the performance of the ...
Flat lens antenna using gap waveguide technology at millimeter waves
(IEEE, 2021)
info:eu-repo/semantics/conferenceObject,
In this paper, a flat lens antenna using Gap Waveguide (GW) technology working in the millimeter waves band was designed. The metamaterial lens is fed using a Groove Gap Waveguide (GGW) horn antenna in order to achieve a ...
Ultrathin sub-terahertz half-wave plate with high conversion efficiency based on zigzag metasurface
(IEEE, 2020)
Artículo / Artikulua,
In this communication, an ultrathin transmissive half-wave plate (HWP) based on a bi-layered zigzag metasurface operating at the lower frequency edge of the terahertz (THz) spectrum is numerically and experimentally studied. ...
Terahertz sensing based on metasurfaces
(Wiley, 2020)
info:eu-repo/semantics/article,
The terahertz (THz) band has very attractive characteristics for sensing and biosensing applications, due to some interesting features such as being a non-ionizing radiation, very sensitive to weak interactions, thus, ...
Tripod-loop metasurfaces for terahertz-sensing applications: a comparison
(MDPI, 2020)
Artículo / Artikulua,
The high electric field intensity achieved on the surface of sensors based on metasurfaces (metasensors) makes them an excellent alternative for sensing applications where the volume of the sample to be identified is tiny ...
