Electrochemical modulation and restructuring of planar metallic metamaterials

Nano-plasmonics as well as the majority of photonic metamaterials rely on resonances of metallic nanostructures. For many applications, it would obviously be desirable to tune these resonances. In this thesis lithographically manufactured gold resonators are presented, whose central frequency and damping properties are modulated by an electrochemical approach. The optical properties of the manufactured samples are investigated experimentally and are confirmed by numerical calculations.
