Figure 2. Active beam-steering metasurface via reversible Cu electrodeposition. (a) Schematic of the electrochemical device for dynamic beam steering. (b) Top-view SEM images of the metasurface before ...
Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...
Space coiling acoustic metamaterials are static and require manual reconfiguration for sound-field modulation. In a new report published in Communications Materials, Christabel Choi, and a team of ...
