One of the main challenges in fabricating metamaterials is given by the difficulty of isotropic deposition of metals on 3D complex structures. Within our group, we optimised a liquid-based deposition technique for such task. The advantages of this technique are manifold (e.g. simple chemistry, intrinsic isotropic technique, fast, cheap …). Still, before reaching the status of a standard approach, it needs further improvement and development.

This project is aimed in obtaining a reliable and simple procedure for Ag deposition on complex structures to be further used in metamaterials fabrication.
