The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

Abstract: This letter proposes a tunable multibeam periodic leaky-wave antenna (LWA) based on radiation of multiple space harmonics. The LWA is composed of a microstrip transmission line and a set of ...

The focus of this paper is to characterize the effects of periodic and aperiodic surface distortions on the performance of membrane reflector antennas. Since the surface of this class of reflector ...
