Flexible control over the directive emissions toward pre‐designed directions has attracted long‐term interest, but available devices suffer from bulky size, limited functionalities, and low efficiencies. Here, a novel anisotropic meta‐atom exhibiting a low polarization cross‐talking was proposed, based on which high‐efficiency metasurfaces with arbitrary polarization‐dependent phase profiles can be easily designed, to realize the desired beam‐control functionalities. The strategy paves the way for the realization of high‐performance multifunctional optical devices with high integration. (Image: H.‐X. Xu et al.; article number 1700045 in this issue)
