Abstract: This letter introduces a novel subarray-configuration method of n × m spiral sequential rotation (SSR) to achieve low cross-polarization level (XPL) and low sidelobe level (SLL) over wide ...
Abstract: Efficient and accurate magnetic target localization methods have important value in navigation, archeology, and other fields. The current scalar positioning technology of magnetic target ...
Two Indian astronomers have used data from Nasa’s James Webb Space Telescope (JWST) to discover an ancient and massive galaxy with two well-defined spiral arms that appears to challenge standard ideas ...
