A Broadband Vortex Beam Generator Based on Single-Layer Hybrid Phase-Turning Metasurface
Vortex beams carrying orbital angular momentum (OAM) have become a research frontier due to the prospect of improving spectral efficiency and transmission capacity in communication systems. In this work, a hybrid phase-turning meta-atom that combines resonance and geometric (Pancharatnam-Berry) phas...
