Cheng-Wei Qiu, Tie Jun Cui, and co-workers present an all-dielectric semispherical lens with functions in shaping 3D wave-propagation paths in article 1600022. The cover image shows principle of the 3D superresolution imaging system, which includes a semispherical magnifying meta-lens and a planar focusing lens. The semispherical lens magnifies signals of the objects located at the core of lens and the focusing lens gathers the magnified signals and focuses them to generate the image of the objects.
