Metageometries for polycyclic aromatic hydrocarbons detection at THz range in food systems
(IEEE, 2021)
Artículo / Artikulua,
Polycyclic aromatic hydrocarbons, when present in food systems, have been shown to have a detrimental effect on human health, producing carcinogenic elements. So, the implementation of processes for their detection and ...
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 ...
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 ...
