Super-Oscillatory Metalens at Terahertz for Enhanced Focusing with Reduced Side Lobes
In this paper, we design and numerically demonstrate an ultra-thin super-oscillatory metalens with a resolution below the diffraction limit. The zones of the lens are implemented using metasurface concepts with hexagonal unit cells. This way, the transparency and, hence, efficiency is optimized, com...
