Performance Analysis of Metalenses Based on Three Kinds of Phase Compensation Techniques
The phase delays introduced by anisotropic nanounits include propagation phase delay, resonant phase delay and geometric phase delay. Various phase devices can be formed based on the metasurfaces consisting of anisotropic nanounits and the phase devices of the same kind function have different perfo...
