We present optical studies of nano-resonators (meta-atoms) which are designed for a specific control of their angular scattering properties in visible light. Directional scattering is obtained by adjusting the series of odd and even scattering modes. The architecture of the meta-atoms is designed to enhance the magnetic dipolar scattering which appears as the major contribution to the odd modes. Several types of meta-atoms are investigated and their scattering properties are measured. We show that the bottom-up approach enables multiple synthetic strategies and we compare their optical efficiencies...
