The cover image shows a shape‐tailored metasurface with the triangular‐lattice arrangement of meta‐atoms, as demonstrated in article number 2001711 by Ling‐Jun Yang, Sheng Sun, and Wei E. I. Sha. The shape‐related manipulation of metasurfaces provides a promising route to control the amplitude of the reflection field, enabling further manipulation of the angular momentum spectrum. The proposed scheme offers an elegant and universal way to manipulate the electromagnetic wave over a wide frequency range, promoting the development of beam‐control applications.
