In a daring maneuver, the joint European Space Agency (ESA) and NASA mission swooped below the solar system’s planetary plane to capture the sun’s elusive south pole. The spacecraft dipped 15 degrees ...

Abstract: In this paper, we propose novel OWC-MIMO modulation scheme which efficiently uses the polar coordinate. Our new optical spatial modulation with polar coordinate is designed to easily adapt ...

Abstract: In this paper, an integrated modeling method for high power microwave ring-focused dual reflector antenna based on coordinate rotation is proposed. The antenna consists of a mode converter, ...
