This paper shows a design method and its verification of a kind of linear-to-circular polarization converter, which allows for high-efficiency polarization conversion with good impedance matching and ...

A wideband circularly polarized (CP) multi-turns plasma helical antenna (HA) with reconfigurable bandwidth is investigated for wireless communications in the x-band. The proposed plasma-based HA is ...

EPFL scientists have developed a new technique that lets researchers watch, with unprecedented sensitivity, how materials ...

Flexible polarization control of the terahertz wave in the wide bandwidth is crucial for numerous applications, such as terahertz communication, material characterization, imaging, and biosensing ...
