Ultrathin and high-efficiency Pancharatnam-Berry phase metalens for millimeter waves
(AIP Publishing, 2021)
Artículo / Artikulua,
Applying the Pancharatnam–Berry (PB) principle to half-wave plate (HWP) metasurfaces allows the manipulation of wavefronts along with the conversion of the handedness of circularly polarized incident waves by simply rotating ...
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, ...
Application of MIR spectroscopy to the evaluation of chemical composition and quality parameters of foal meat: a preliminary study
(MDPI, 2020)
info:eu-repo/semantics/article,
The aim of this work was to study the potential of mid-infrared spectroscopy to evaluate the chemical composition and quality parameters of foal meat according to differences based on slaughter ages and finishing diets. ...
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. ...
Bull’s-eye antenna with circular polarization at millimeter waves based on ridge gap waveguide technology
(IEEE, 2021)
Artículo / Artikulua,
In this communication, a Bull’s-Eye (BE) antenna with circular polarization (CP) based on ridge gap waveguide (RGW) technology is numerically and experimentally demonstrated. The structure is excited from the bottom with ...
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 ...
Compact groove diamond antenna in gap waveguide technology with broadband circular polarization at millimeter waves
(IEEE, 2020)
Artículo / Artikulua,
In this paper, three compact antennas using the Ridge Gap Waveguide (RGW) technology working in the millimeter-wave band (60 GHz), with a high-purity and broadband circular polarization (CP) are numerically and experimentally ...
