recommendations! Published in 2024 at "Optical and Quantum Electronics"

DOI: 10.1007/s11082-024-07203-y

Abstract: In this paper, a planar OAM reconfigurable plasma reflective metasurface with size 30 × 30 cm2 is designed. It consists of the reconfigurable plasma metasurface reflector and a feed horn antenna. The phase distribution of the plasma… read more here.

DOI: 10.1063/1.5081514

Abstract: In this paper, a single-layer transmissive metasurface (TMS) is designed to generate orbital angular momentum (OAM) vortex waves with homogeneous radiation at microwave frequencies (e.g., 10 GHz). A single-layer TMS with the thickness of 3 mm (0.1λ0)… read more here.

DOI: 10.1109/access.2020.3007494

Abstract: In this paper, we propose a method to generate a high-order Bessel orbital angular momentum (OAM) vortex beam by using a single-layer reflective metasurface, which integrates the advantages of small size, high efficiency, insensitive polarization… read more here.

DOI: 10.1364/oe.522316

Abstract: Phase modulated metasurface (PMM) can control the transmission state of electromagnetic (EM) wave through phase modulation scheme on the interface. Orbital angular momentum (OAM) vortex wave is denoted by the helical phase distribution of the… read more here.
