ASKAP Radio Telescope Spots Unusual 54-Minute Repeating Signal from Distant Space ObjectA groundbreaking discovery has been made by the ASKAP (Australian Square Kilometer Array Pathfinder) radio telescope, which ...
A circular polarization (CP) folded reflectarray antenna is proposed at the 30 GHz band. A five-layered circular polarization selective metasurface (CPSM) is introduced to realize the path folding for ...
By leveraging polarization beating arising from the spatially engineered superposition of four circularly polarized (CP) components with distinct spatial frequencies, the proposed metasurface enables ...
