Abstract: A design methodology for a frequency-controlled beam-pointing high gain antenna based on a system of a large reflector and a subreflectarray at the 77-GHz band is presented. This system ...

Abstract: Metasurface reflectors have been applied to microwave wireless power transfer (WPT) for transmitting power to IoT devices that are placed at arbitrary locations. In this paper, a multi-beam ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...
