This work involves the design, fabrication and characterization of metamaterials based on meta-atoms and its assemblies. The aim is to tailor the optical properties that emerge from choosing material and geometry of their basic unit cells. The approach starts with the bottom-up preparation of nanoresonators, which consist in core-shell structures made of plasmonic nanoparticles covering a dielectric core. The coupling between the plasmonic units leads to new plasmon resonances that have a magnetic dipole character. The next step involves the meta-atoms organization on surfaces and the characterization of their structural and optical properties. Highly ordered monolayers and patterns of meta-atoms over large area were obtained via blade coating deposition. The samples are then characterized by spectral high-resolution interference microscopy, which provides information on the scattering intensity and the phase shift induced by the meta-atom. In this way, the scattering response of different meta-atoms is studied in an unprecedented manner.
