Compact bull's-eye antenna in ridge gap waveguide with circular polarization at 60 GHz
(IEEE, 2021)
info:eu-repo/semantics/conferenceObject,
In this work, a Bull's-Eye (BE) antenna with circular polarization (CP) based on ridge gap waveguide (RGW) technology, working in the millimeter-wave band (60 GHz) is numerically and experimentally demonstrated. The structure ...
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 ...
