Sulfur is one of the most abundant elements in the universe. If you peer into a diffuse interstellar cloud, you find loads of it—about the amount expected based on fusion patterns in the stars it was ...
Abstract: This communication proposes a radiation pattern reconfigurable circularly polarized antenna based on liquid dielectric. The antenna consists of a circularly polarized feeding antenna and a 3 ...
Abstract: Under high-dynamic conditions, star sensors often capture images with low signal-to-noise ratio (SNR). Image restoration can mitigate energy dispersion from star trailing, but it is ...
