Abstract: Orbital angular momentum (OAM) has attracted attention since it could provide infinite orthogonal channels and effectively improve spectrum utilization in free-space optical communications.

Abstract: In this communication, a beam-space semidefinite relaxation (BS-SDR) method is presented for synthesizing shaped power patterns of arbitrary antenna arrays. Different from the original ...
