Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...
Abstract: An ultralow-profile decoupling patch (DP) structure is proposed for E-plane microstrip antenna arrays. Without requiring ground modification or complex circuitry, the DP introduces a ...
Abstract: Achieving in-band radar cross section (RCS) in ultrawideband (UWB) phased array antennas (PAAs) is fundamentally constrained by the intrinsic coupling between radiation and scattering. This ...
