Abstract: We present a short overview on the research works related to two hot topics in metamaterials: transparent metals and inhomogeneous meta-surfaces. For the first topic, we first introduce a scattering-cancellation mechanism for making continuous metals optically transparent, and then propose a realistic design in optical domain, and finally experimentally prove the idea in both microwave and terahertz frequency domains. For the second topic, we show that light reflection/refraction at a carefully designed gradient-index meta-surface follows a generalized Snell's law, and then demonstrate that such a system can perfectly convert a propagating electromagnetic wave to a surface wave under certain conditions, and finally introduce several interesting applications of this type of systems.

Keywords: Metamaterials, Transparent metal, Terahertz, Scattering cancellation mechanism.
