Compact antennas in ridge gap waveguide with circular polarization
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
In this paper, two compact antennas in Ridge Gap Waveguide (RGW) technology, working at 60 GHz, with a high-purity circular polarization (CP) within a broad bandwidth are manufactured and measured. The antennas are fed ...
Silicon carbide as a material-based high-impedance surface for enhanced absorption within ultra-thin metallic films
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
The absorption of infrared radiation within ultra-thin metallic films is technologically relevant for different thermal engineering applications and optoelectronic devices, as well as for fundamental research on sub-nanometer ...
A gap waveguide fed circular polarization antennas in the millimeter wave range
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
In this work, a novel circular polarization (CP) antennas in ridge gap waveguide (RGW) working in the V-band of the millimeter-wave spectrum is presented. CP is generated in a simple and effective way by means of two ...
Lipid and protein oxidation marker compounds in horse meat determined by MIR spectroscopy
(MDPI, 2020)
info:eu-repo/semantics/article,
This work broadens the study of lipid and protein oxidation marker compounds in foal meat, employing the technology of Attenuated Total Reflectance-Fourier Transform Mid-Infrared Spectroscopy (ATR-FT/MIR, shortened in the ...
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 ...
Revealing the underlying mechanisms behind TE extraordinary THz transmission
(Chinese Laser Press, 2020)
Artículo / Artikulua,
Transmission through seemingly opaque surfaces, so-called extraordinary transmission, provides an exciting plat- form for strong light–matter interaction, spectroscopy, optical trapping, and color filtering. Much ofthe ...
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. ...
Metal 3D printed D-Band waveguide to surface wave transition
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
The coupling efficiency between free space waves and surface waves is low, narrowband, or both. Highly efficient broadband (better than 20% fractional bandwidth) coupling from waveguide modes can be achieved through ...
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, ...
