Can one size really fit all? The authors demonstrate the versatility of a graphene-based metasurface that is capable of actively controlling anomalous beam steering, focusing, cloaking, and illusion optics. These various functionalities are usually discussed in disparate fashion, but this work shows that they can all be described within a general framework for arbitrary surface morphology. This unified, simplified approach seems quite appealing for device design.
