Phase-Controlled Planar Metalenses for High-Resolution Terahertz Focusing

Phase-Controlled Planar Metalenses for High-Resolution Terahertz Focusing

We experimentally demonstrate that high-resolution terahertz focusing can be realized in planar metalenses, which consist of arrays of different V-shaped antenna units on a silicon substrate. Numerical results show that a larger numerical aperture of metalenses can provide smaller full width at half...
