Dielectric Metalens for Superoscillatory Focusing Based on High-Order Angular Bessel Function

Dielectric Metalens for Superoscillatory Focusing Based on High-Order Angular Bessel Function

The phenomenon of optical superoscillation provides an unprecedented way to solve the problem of optical far-field label-free super-resolution imaging. Numerous optical devices that enable superoscillatory focusing were developed based on scalar and vector diffraction theories in the past several ye...
