| dc.description.abstract | The orbital angular momentum (OAM) communication has infinite channel capacity and accuracy. However, current generators for vortex beam have a limitation of large divergence angle. To solve this issue, we propose a meta-lens concept to decrease divergence angle of vortex beam using reflective metasurface. we designed square-shape antennas which cover 360˚ phase to generate vortex beam and simulated the generation vortex beam with a topological charge l=1. The divergence angle of each vortex beam is decreased from 16˚ to 8˚. | - |
