In article number 1700309 , Ting Xu and co‐workers create a large‐area nanowire metamaterial which strongly discriminates the light based primarily on the angle of incidence at visible frequencies; only the light very close to the normal incidence can be well transmitted through the metamaterial with high transmission efficiency, while the light from other directions is completely blocked. The nanowire metamaterial with narrow angular optical transparency window is a good potential candidate to alleviate the diffraction effect and significantly improve imaging quality for lens‐less imaging technology.
