Abstract: In this paper, a multifunctional scattering antenna array has been proposed to generate orbital angular momentum (OAM) vortex scattering wave and meanwhile reduce antenna radar cross section ...

Abstract: In this article, we propose a method based on the aperture antennas theory to understand the limitations of orbital angular momentum (OAM) antennas in far-field links. Additional insight is ...

Leaders with Savage & Associates say their organization was founded on philanthropy, so the opportunity to give back to local pediatric patients is a no brainer.
