Abstract: We compare the technique of using the orbital angular momentum (OAM) of radio waves for generating multiple channels in a radio communication scenario with traditional ...

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 ...

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.
